I had a look at a few sub folders in C:\ProgramData and these have special permissions set that looks like they should be ok
I think I might try this and see if works ok.

I've been using this for application specific data storage shared by any user. However, I just looked at the permissions: ProgramData NT AUTHORITY\SYSTEM:(OI)(CI)(F) BUILTIN\Administrators:(OI)(CI)(F) CREATOR OWNER:(OI)(CI)(IO)(F) BUILTIN\Users:(OI)(CI)(RX) BUILTIN\Users:(CI)(WD,AD,WEA,WA) And I think I've made a boo boo. The CREATOR OWNER has full control, so if I run an app as one user it may fail as another user. I'll have to check this out to be sure I'm using the correct folder. Sorry I didn't answer your question, I just noticed this issue after reading your problem. Greg
