Like others, I am having troubles with My Photo Index crashing on load.
The program will load up and ask if I'd like a new or existing database file.  After choosing a file, it will think for a moment, then give me a JIT error, and ask if I'd like to continue or quit.  If I continue, I can still use the menus, but when I try to import, it gives me another error at the "Let us help you tag your images" part.  Finally, when I hit import, it will go through all my images, then give me a third error and freeze without closing the import dialog.

My System
HP Pavilion 9720us laptop
Windows XP Pro SP3
.Net Framework 3.5 SP1
OS, drivers, and .Net framework all completely updated.

Attempted Solutions

1. Redownload My Photo Index and reinstall.  Same problem.
2. Uninstall .Net Framework 2.  Won't let me, says some programs still need it.
3. Reinstall .Net Framework 2.  Won't let me, crashes.
4. Reinstall .Net Framework 3.5 SP1.  Reinstalled just fine, same problem.
5. Install the MDAC.  Won't let me, says it's "included with this version of Windows."  Also, running the "Microsoft Component Checker" says it's installed just fine.
6. Install the Microsoft SQL Server Native Client.  Same problem.

Thank you for the quick reply, Asaf!

Yes, the registry key is correct, and I think I found the problem (on my end).  The solution was found here.
I now have a feature request essential for my usage of the program, but I'll save this selfish request for the appropriate forum.

Thanks again!
