Need help with per user installation

[PPro]

Can I use ALLUSERS=2 and MSIINSTALLPERUSER=1 and then [ProgramFilesFolder] to achieve a per-user installation (even for admin users)? In this case it would actually install the files to [LocalAppDataFolder]? Is that the better approach?

I'm experimenting with creating a per user installer. I want each user to have their own registry settings in HKCU, and their own exe files in the [LocalAppDataFolder]. I set ALLUSERS = "" and 'Priveliges required' to 'limited' in the project properties. When I build my project, I'm getting and ICE38 and ICE64 errors:

How do I solve these?
