The commands below all adjust attributes of the installer. These attributes control how the installer looks and functions, including which pages are present in the installer, as what text is displayed in each part of each page, how the installer is named, what icon the installer uses, the default installation directory, what file it writes out, and more. Note that these attributes can be set anywhere in the file except in a \R{ssection}{Section} or \R{ffunction}{Function}.
Adds a branding image on the top, bottom, left, or right of the installer. Its size will be set according to the width/height specified, the installer width/height and the installer font. The final size will not always be what you requested; have a look at the output of the command for the actual size. Because this depends on the installer font, you should use \R{asetfont}{SetFont} before \R{aaddbrandingimage}{AddBrandingImage}. The default padding value is 2.
\R{aaddbrandingimage}{AddBrandingImage} only adds a placeholder for an image. To set the image itself on runtime, use \R{setbrandingimage}{SetBrandingImage}.
Controls whether or not installs are enabled to the root directory of a drive, or directly into a network share. Set to 'true' to change the safe behavior, which prevents users from selecting C:\\ or \\\\Server\\Share as an install (and later on, uninstall) directory. For additional directory selection page customizability, see \R{onverifyinstdir}{.onVerifyInstDir}.
Specifies the font used to show the text on the background gradient. To set the color use \R{abggradient}{BGGradient}. If no parameters are specified, the default font will be used. The default font is bold and italic Times New Roman.
Specifies whether or not to use a gradient background window. If 'off', the installer will not show a background window, if no parameters are specified, the default black to blue gradient is used, and otherwise the top_color or bottom_color are used to make a gradient. Top_color and bottom_color are specified using the form RRGGBB (in hexadecimal, as in HTML, only minus the leading '#', since # can be used for comments). 'textcolor' can be specified as well, or 'notext' can be specified to turn the big background text off.
Sets the text that is shown (by default it is 'Nullsoft Install System vX.XX') at the bottom of the install window. Setting this to an empty string ("") uses the default; to set the string to blank, use " " (a space). If it doesn't matter to you, leave it the default so that everybody can know why the installer didn't suck. heh. Use /TRIMLEFT, /TRIMRIGHT or /TRIMCENTER to trim down the size of the control to the size of the string.
When used outside a \R{pageex}{PageEx} block: Sets the text for the titlebar of the installer. the By default, it is 'Name Setup', where Name is specified with the \R{aname}{Name} instruction. You can, however, override it with 'MyApp Installer' or whatever. If you specify an empty string (""), the default will be used (you can however specify " " to achieve a blank string).
Replaces dialog (\e{IDD_LICENSE}, \e{IDD_DIR}, \e{IDD_SELCOM}, \e{IDD_INST}, \e{IDD_INSTFILES}, \e{IDD_UNINST} or \e{IDD_VERIFY}) by a dialog with the same resource ID in ui_file.exe. You can also specify 'all' as the dialog if you wish to replace all 7 of the dialogs at once from the same UI file. For some example UIs look at Contrib\\UIs under your NSIS directory.
\b \e{IDD_INST} must contain \e{IDC_BACK} (button), \e{IDC_CHILDRECT} (static control the size of all other dialogs), \e{IDC_VERSTR} (static), \e{IDOK} (button), and \e{IDCANCEL} (button). If an image control (static with \e{SS_BITMAP} style) will be found in this dialog it will be used as the default for \R{setbrandingimage}{SetBrandingImage}.
This bitmap should have a size of 96x16 pixels, no more than 8bpp (256 colors) and contain six 16x16 images for the different states (in order: selection mask, not checked, checked, greyed out, unchecked & read-only, checked & read-only). Use magenta as mask color (this area will be transparent).
Specifies whether or not the installer will perform a CRC on itself before allowing an install. Note that if the user uses /NCRC on the command line when executing the installer, and you didn't specify 'force', the CRC will not occur, and the user will be allowed to install a (potentially) corrupted installer.
Specifies which variable is to be used to contain the directory selected. This variable should contain the default value too. This allows to easily create two different directory pages that will not require you to move values in and out of $INSTDIR. The default variable is $INSTDIR. This can only be used in \R{pageex}{PageEx} and for directory and uninstConfirm pages.
If `\R{adirverify}{DirVerify} leave' is used, the Next button will not be disabled if the installation directory is not valid or there is not enough space. A flag that you can read in the leave function using \R{getinstdirerror}{GetInstDirError} will be set instead.
Replaces the default text that comes up when a file cannot be written to. This string can contain a reference to $0, which is the filename ($0 is temporarily changed to this value). Example: "Can not write to file $\\r$\\n$0$\\r$\\ngood luck.".
Sets the icon of the installer. Every icon in the icon file will be included in the installer. Use \R{auninstallicon}{UninstallIcon} to set the uninstaller icon.
Sets the colors to use for the install info screen (the default is 00FF00 000000. Use the form RRGGBB (in hexadecimal, as in HTML, only minus the leading '#', since # can be used for comments). Note that if "/windows" is specified as the only parameter, the default windows colors will be used.
Sets the default installation directory. See the \R{variables}{variables section} for variables that can be used to make this string (especially $PROGRAMFILES). Note that the part of this string following the last \\ will be used if the user selects 'browse', and may be appended back on to the string at install time (to disable this, end the directory with a \\ (which will require the entire parameter to be enclosed with quotes). If this doesn't make any sense, play around with the browse button a bit.
This attribute tells the installer to check a string in the registry, and use it for the install dir if that string is valid. If this attribute is present, it will override the \R{ainstalldir}{InstallDir} attribute if the registry key is valid, otherwise it will fall back to the \R{ainstalldir}{InstallDir} default. When querying the registry, this command will automatically remove any quotes. If the string ends in ".exe", it will automatically remove the filename component of the string (i.e. if the string is "C:\\Program Files\\Foo\\app.exe", it will know to use "C:\\Program Files\\Foo"). For more advanced install directory configuration, set $INSTDIR in .onInit.
Valid values for flag are "smooth" (smooth the progress bar) or "colored" (color the progress bar with the colors set by \R{ainstallcolors}{InstallColors}. Examples: "InstProgressFlags" (default old-school windows look), "InstProgressFlags smooth" (new smooth look), "InstProgressFlags smooth colored" (colored smooth look whee). Note: neither "smooth" or "colored" work with \R{axpstyle}{XPStyle} on when the installer runs on Windows XP with a modern theme.
Adds an install type to the install type list, or disables the custom install type. There can be as many as 32 types, each one specifying the name of the install type. If the name is prefixed with 'un.' it is an uninstaller install type. The name can contain variables which will be processed at runtime before the components page shows. Another way of changing the \R{ainsttype}{InstType} name during runtime is the \R{sinsttypesettext}{InstTypeSetText} command. The difference is that with \R{sinsttypesettext}{InstTypeSetText} you are saving your precious user variables. The first type is the default (generally 'Typical'). If the /NOCUSTOM switch is specified, then the "custom" install type is disabled, and the user has to choose one of the pre-defined install types. Alternatively, if the /CUSTOMSTRING switch is specified, the parameter will override the "Custom" install type text. Alternatively, if the /COMPONENTSONLYONCUSTOM flag is specified, the component list will only be shown if the "Custom" install type is selected.
Sets the background color of the license data. Color is specified using the form RRGGBB (in hexadecimal, as in HTML, only minus the leading '#', since # can be used for comments). Default is '/gray'. You can also use the Windows OS defined color by using '/windows'.
Specifies a text file or a RTF file to use for the license that the user can read. Omit this to not have a license displayed. Note that the file must be in the evil DOS text format (\\r\\n, yeah!). To define a multilingual license data use \R{licenselangstring}{LicenseLangString}.
Specifies if the displayed license must be accept explicit or not. This can be done either by a checkbox or by radiobuttons. By default the "next button" is disabled and will only be enabled if the checkbox is enabled or the right radio button is selected. If off is specified the "next button" is enabled by default.
Declare that the installer is DPI-aware. A DPI-aware application is not scaled by the DWM (DPI virtualization) so the text is never blurry. NSIS does not scale the bitmap used by the tree control on the component page and some plugins might have compatibility issues so make sure that you test your installer at different DPI settings if you select \e{true}.
See \W{http://msdn.microsoft.com/en-us/library/dd464660}{MSDN} for more information about DPI-aware applications.
Declare that the installer is compatible with the specified Windows version(s). This adds a SupportedOS entry in the compatibility section of the application manifest. The default list of Win7+Win8+Win8.1 will probably be updated to include newer Windows versions in the future. \e{none} is the default if \R{arequestexecutionlevel}{RequestExecutionLevel} is set to \e{none} for compatibility reasons.
Sets the name of the installer. The name is usually simply the product name such as 'MyApp' or 'CrapSoft MyApp'. If you have one or more ampersands (&) in the name, set the second parameter to the same name, only with doubled ampersands. For example, if your product's name is "Foo & Bar", use:
\c Name "Foo & Bar" "Foo && Bar"
If you have ampersands in the name and use a \R{langstring}{LangString} for the name, you will have to create another one with doubled ampersands to use as the second parameter.
Specifies the output file that the MakeNSIS should write the installer to. This is just the file that MakeNSIS writes, it doesn't affect the contents of the installer.
Specifies the requested execution level for Windows Vista and higher. The value is embedded in the installer and uninstaller's XML manifest and tells Windows which privilege level the installer requires. \e{user} requests the a normal user's level with no administrative privileges. \e{highest} will request the highest execution level available for the current user and will cause Windows to prompt the user to verify privilege escalation. The prompt might request for the user's password. \e{admin} requests administrator level and will cause Windows to prompt the user as well. Specifying \e{none}, which is also the default, will keep the manifest empty and let Windows decide which execution level is required. Windows automatically identifies NSIS installers and decides administrator privileges are required. Because of this, \e{none} and \e{admin} have virtually the same effect.
It's recommended, at least by Microsoft, that every application is marked with a required execution level. Unmarked installers are subject to compatibility mode. Workarounds of this mode include automatically moving any shortcuts created in the user's start menu to all users' start menu. Installers that need not install anything into system folders or write to the local machine registry (HKLM) should specify \e{user} execution level.
Sets the installer font. Please remember that the font you choose must be present on the user's machine as well. Don't use rare fonts that only you have.
Sets whether or not the details of the install are shown. Can be 'hide' to hide the details by default, allowing the user to view them, or 'show' to show them by default, or 'nevershow', to prevent the user from ever seeing them. Note that sections can override this using \R{setdetailsview}{SetDetailsView}.
Sets whether or not the details of the uninstall are shown. Can be 'hide' to hide the details by default, allowing the user to view them, or 'show' to show them by default, or 'nevershow', to prevent the user from ever seeing them. Note that sections can override this using \R{setdetailsview}{SetDetailsView}.
Specifies whether or not the installer should be silent. If it is 'silent' or 'silentlog', all sections that have the SF_SELECTED flag are installed quietly (you can set this flag using \R{sectionsetflags}{SectionSetFlags}), with no screen output from the installer itself (the script can still display whatever it wants, use \R{messagebox}{MessageBox}'s /SD to specify a default for silent installers). Note that if this is set to 'normal' and the user runs the installer with /S (case sensitive) on the command line, it will behave as if \R{asilentinstall}{SilentInstall} 'silent' was used. Note: see also \R{logset}{LogSet}.
Specifies whether or not the uninstaller should be silent. If it is 'silent' or 'silentlog', the uninstall section will run quietly, with no screen output from the uninstaller itself (the script can still display whatever it wants, use \R{messagebox}{MessageBox}'s /SD to specify a default for silent installers). Note that if this is set to 'normal' and the user runs the uninstaller with /S on the command line, it will behave as if \R{asilentuninstall}{SilentUnInstall} 'silent' was used. Note: see also \R{logset}{LogSet}.
If parameters are specified, overrides the space required and space available text ("Space required: " and "Space available: " by default). If 'none' is specified as the required text no space texts will be shown.
Overrides the subcaptions for each of the installer pages (0=": License Agreement",1=": Installation Options",2=": Installation Directory", 3=": Installing Files", 4=": Completed"). If you specify an empty string (""), the default will be used (you can however specify " " to achieve a blank string).
You can also set a subcaption (or override the default) using \R{acaption}{Caption} inside a \R{pageex}{PageEx} block.
Changes the text of the button that by default says "Uninstall" in the uninstaller. If no parameter is specified, the default text is used. See also \R{writeuninstaller}{WriteUninstaller} (replaces UninstallEXEName).
Sets what the titlebars of the uninstaller will display. By default, it is 'Name Uninstall', where Name is specified with the Name command. You can, however, override it with 'MyApp uninstaller' or whatever. If you specify an empty string (""), the default will be used (you can however specify " " to achieve a blank string).
Accepts variables. If variables are used, they must be initialized in \R{unonInit}{un.onInit}.
Sets the default subcaptions for the uninstaller pages (0=": Confirmation",1=": Uninstalling Files",2=": Completed"). If you specify an empty string (""), the default will be used (you can however specify " " to achieve a blank string).
You can also set a subcaption (or override the default) using \R{acaption}{Caption} inside a \R{pageex}{PageEx} block.
Sets whether or not an XP manifest will be added to the installer. An XP manifest makes the installer controls use the new XP style when running on Windows XP. This affects the uninstaller too.
