Hi. I've been having problems with MSE recently and I decided to reinstall it but I've come into a couple of problems; first, I couldn't seem to uninstall the program, instead resorting to a brute force method to remove it, secondly I keep getting the error (0x80070645) whenever I try to install. I don't know how I can get it to produce a log but I don't know what's happening that's causing this error to happen. I checked to see if the update key was there to remove but no luck, I cleaned up and reinstalled various .NET frameworks. I even ran sfc /scannow but there is nothing wrong. I don't know what else to do besides reformatting (which I really don't want to to.) and everything I tried just places me at a brick wall; what am I supposed to do? Also of note, I can't seem to remove .NET Framework 3.5 from my computer to instal it via Add/Remove programs, it always seems to fail at 98% reverting all of the changes it has done. Again, I have cleaned up the install, I have ran ComboFix, I ran sfc /scan now but nothing seems to work, any suggestions?
