Unable to uninstall visual studio 2012 - Getting an exception thrown?

Question

I'm trying to uninstall VS2012 to install VS2013 - But before I uninstall it from the control panel, I went ahead and removed other seemingly unrelated components that I never use. Mainly, I removed all the SQL-related stuff, all the ASP.NET stuff, F# runtime, Async SKD and some more stuff - I never use those. Plus everytime I uninstall VS those components remain, annoying... After I did that, and tried to uninstall VS12 Ultimate - I got an exception!

I clicked on details, and got:

I tried a lot of ways, other uninstallers (they all run the same uninstaller and thus I get the same crash) - I tried booting up the installation medium, running it from cmd with the args /uninstall /force - No dice...

How should I uninstall it now?

PS: Running Windows 7 X64 Ultimate

Thanks for any help.

EDIT: MS Crosslink

EDIT: Now I removed literally everything VS-related - And cleaned the registry - it's not even there in the control panel anymore - Still can't install VS2013...

EDIT: I installed VS10 - Just to see if it was really those components that I removed that are causing the problem - It didn't help.

EDIT: Someone mentioned that updating your graphics card and disabling the wpf graphics hardware acceleration might help - Since the splash screen is implemented in wpf - The settings are said to be in HKCU/SOFTWARE/Microsoft/Avalon.Graphics/DisableHWAcceleration But I didn't find that key - I created it with no avail... - I also just updated my graphics card, no dice...

Thanks for anyone who tried to help. Unfortunately I ended up formatting, as none of the solutions I tried really worked. M$, I sincerely hate you! - Lesson learned I guess, don't F with M$, it doesn't F with you.
