Solution found...I forgot about being able to run programs in compatibility mode. Here's what you do. Save the MSI file to the c: drive. Open CMD line and run "msiexec /i PStory.msi NOLEGITCHECK=1 SKIPOSCHECK=1". Once the install is done, copy and paste the shortcut for the program into the "all users" folder (or public on Win7/2k8) On that shortcut, right click, go to compatibility tab, run in XP SP3 mode and run for all users (it's a button down below).
Hope this helps. Let me know if there are any questions.
