Hi Rick,
In case you haven't already seen it, check out the Inno Setup Help file re the "ArchitectureInstallIn64BitMode" setting in the [Setup] section. It links to the "Install Mode: 32-bit vs. 64-bit" Help page, which also has good info. ------------------- I had seen this reference, but stopped at: "Normally, you should not change this directive from its default value unless your application contains native 64-bit binaries" Which is not the case But then I see in the "Install Mode: 32-bit vs 64-bit" topic, it says: "64-bit mode is selected if the user is running a 64-bit version of Windows and the system's processor architecture is included in the value of the ArchitecturesInstallIn64BitMode [Setup] section directive. Otherwise, 32-bit mode is used." Starts off good by saying "64-bit mode is selected if the user is running a 64-bit version of Window", but then it muddies the waters with "and the system's processor architecture is included in the value of the ArchitecturesInstallIn64BitMode [Setup] section directive. Otherwise, 32-bit mode is used." Then, looking back at the choices for "ArchitectureInstallIn64BitMode", it lists x64 and ia64. http://www.tomshardware.com/forum/68071-28-what-ia64 suggests that we're not likely to be dealing with ia64 soon My sense is that this is leading to 2 SETUP.EXE's being required, 1 for 32 bit, and 1 for 64 bit, with the one for x64 taking into account the limitations discussed in "64-bit Installation Limitations" I really don't want 2 SETUP.EXEs - and I imagine I'm not alone. On the limitations, this one ... I read a few times and not sure I understand it: "The System32 path returned by the {sys} constant does not always map to the 64-bit System directory. When Setup/Uninstall is running in 64-bit mode, it maps to the 64-bit System directory when used in the [Dirs], [Files], [InstallDelete], [Run], [UninstallDelete], and [UninstallRun] sections because Setup temporarily disables WOW64 file system redirection [external link] when files/directories are accessed by those sections. Elsewhere, System32 and {sys} map to the 32-bit System directory, as is normal in a 32-bit process." I think it's saying that it disables WOW64 redirection (which I assume would be performed by Windows) because in these sections it's already targeting the 64 bit folder (sysWOW64), so redirection isn't needed or harmful.
