Lightroom - .lrcat and default Program!

So the problem:

At some point Windows Vista 64bit changed the default program for my lrcat files to Adobe Professional. I think it was around the time I installed Lightroom 3 Beta.

The result, I was unable to double click on any Lightroom Catalog file and have Lightroom open. It would try to open the file in Adobe Professional software instead, BOOOOOO!

In the past to fix the problem you could right click the file goto >open with>choose default program.... But Lightroom wasn't an option, and when I tried browsing to the lightroom.exe and clicking on that, it still wouldn't open the file in Lightroom.

The fix (finally) - try this at your own risk, attempting to modify the registry can make the operating system unstable.

open the Program "regedit.exe"

goto:
computer\Hkey_classes_root\AdobeLightroom.lrcat\shell\open\command

In there you will need to add or change the "default" string to the location of the Lightroom version you are using, 2.5 in my case.
for example> "C:\Program Files\Adobe\Adobe Photoshop Lightroom 2.5\lightroom.exe"

Log out, log back in. problem solved....
