Hi,
I have an app that uses both .mdf and .mdb files... this app has not been able to run on Vista and just now going in and changing the setup installer.

We have moved the .mdf and .mdb files out of Program Files and changed our software code to point to new locations in ProgramData (is that the correct place?)

Regardless when we run on Vista it still gives an error that the app cannot write to it.

I searched the forums for .mdf file and found only one post that did not help.
