=SetRegView=

<ins>32</ins>|64|lastused

Sets the registry view affected by 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 SetRegView 64 allows the installer to access keys in the x64 view of the registry.

Affects [[Reference/DeleteRegKey|DeleteRegKey]], [[Reference/DeleteRegValue|DeleteRegValue]], [[Reference/EnumRegKey|EnumRegKey]], [[Reference/EnumRegValue|EnumRegValue]], [[Reference/ReadRegDWORD|ReadRegDWORD]], [[Reference/ReadRegStr|ReadRegStr]], [[Reference/WriteRegBin|WriteRegBin]], [[Reference/WriteRegDWORD|WriteRegDWORD]], [[Reference/WriteRegStr|WriteRegStr]] and [[Reference/WriteRegExpandStr|WriteRegExpandStr]].

Does not affect [[Reference/InstallDirRegKey|InstallDirRegKey]]. Instead, the registry can be read using [[Reference/ReadRegStr|ReadRegStr]] in [[Reference/.onInit|.onInit]].
