Can't make LR3.5 default for .cr2 on Windows 7

Question

I am wondering if this is a bug or if I am slowly losing my mind When I try to make LR the default program for these files (left-clicking> set default program> browse> select LR), it is like it doesn't go through. LR still does not show up as the default program. I have been using LR for awhile now and loved it until this odd glitch. Is there a way to uninstall the last update?

Try this:
Right-click a raw file, choose "Open with".  If Lightroom doesn't appear in the list (it won't initially), choose "Choose default program...".  Lightrom probably won't be in the "Recommended Programs" list the first time you do this, but scroll down to the bottom to "Other Programs".  This may be empty, so click on "Browse...".  Navigate to the Lightroom program folder, which will be something like "C:\Program Files\Adobe\Adobe Photoshop Lightroom  3.5" and then select lightroom.exe. 
Personally, I would uncheck "Always use the selected program to open this kind of file", but your choice.
This should open Lightroom, but I think LR3.x will always open the import dialog, showing the folder containing the file you selected as a folder to import from, even if the file itself is already in the catalog. 
This doesn't do what you want, I'm afraid. 
"After the update, I was not able to find a specific photo in it's folder, so I checked the folder outside of LR and the picture was still where it was supposed to be"
I'm not sure I understand that!  When I import files or folders in Lightroom, the folder structure inside Lightroom is exactly the same as the folder structure outside (except that I see only folders containing files I've imported).  So if I know where to find a photo in Windows Explorer, then I also know where to find it in LR - as they're exactly the same place:
Or perhaps I've misunderstood your problem?
