 Sets the registry view affected by \R{registry}{registry commands}. On Windows x64 there are two views. One for 32-bit applications and one for x64 applications. By default, 32-bit applications running on x64 systems under WOW64 have access only to the 32-bit view. Using \c{SetRegView 64} allows the installer to access keys in the x64 view of the registry.
