Need help with per user installation

[PPro]

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:

C:\Users\sen\workspace\ProduceProClient\MSI Factory\Build Files\ProduceProClient.wxs(286) : error LGHT0204 : ICE38: Component pproclient.exe installs to user profile. It must use a registry key under HKCU as its KeyPath, not a file.

C:\Users\sen\workspace\ProduceProClient\MSI Factory\Build Files\ProduceProClient.wxs(264) : error LGHT0204 : ICE64: The directory INSTALLDIR is in the user profile but is not listed in the RemoveFile table.

How do I solve these?

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?
