I ran into some trouble while trying to install .net framework. My laptop (sony vaio vgn cr41z if it matters) running on windows 7 x64, just shuts down during the installation process. No blue screen, no error message, no logout screen, no nothing. No errors even when I reboot. I had a look into this error log:
I searched stackoverflow for similar problems, but all I found was applications developed under various versions of .net crashing with the same error code (80131506). I tried to install .net 3.5, 4.0 and 4.5. Standalone installer, web installer, even via Windows Update. The same problem...
LE: I think this is a hardware or driver issue. I even changed the OS (Windows 8 Pro x64) and the problem wouldn't go. Good thing I have my desktop near. :)
