Hi Doug

>The only problem with ProgramData is that while it's read-write for the user that creates the folder, it's read-only for other users (unless you change folder permissions).

Have you tried writing to ProgramData using a VFP app that has a manifest built into it?

I have added a manifest to my app using Calvin Hsia's code that sets the requestExecutionLevel to 'asInvoker'.

I then carried out some tests using an Admin User and a Standard User and with UAC on and off.

It appears to me that c:\ProgramData is treated differently to c:\Program Files and c:\Windows. As far as I can tell my app with a manifest was able to successfully write to c:\ProgramData regardless of the User type or the UAC setting I chose, so even a lowly Standard User with UAC turned on was able to do it. I should stress that adding a manifest prevents virtualizaton from occuring so these were real writes and were not writes to a copy of the file in the VirtualStore.

I am concerned that nobody has yet come up with a clear indication of what should be done where we want to install an application that has data which is not user-specific. I would like to have my findings confirmed or disproved if anyone is interested enough to investigate this.
