Is your app running as 32-bit?

Just to note (looking at the MSDN reference you mentioned):

FOLDERID_ProgramFilesX64
This value is not supported on 32-bit operating systems. It also is not 
supported for 32-bit applications running on 64-bit operating systems. 
Attempting to use FOLDERID_ProgramFilesX64 in either situation results 
in an error. See Remarks for more information.

So even if we did move to FOLDERIDs it wouldn't make much difference if 
the app is 32-bit as 32-bit apps won't return 64-bit related OS paths 
(it seems).

If the app is running as 64-bit then I think the relevant CSIDLs return 
the right thing?

Warmest Regards,

Mark.
