Commented Unassigned: Can't start MCEBuddy service [1638]

MCE Buddy 2.13.12 was working OK on my system but then I disabled it, along with a bunch of other stuff, to diagnose my slow boot times. Now, when I try and start it I get these errors:

Application: MCEBuddy.Service.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an internal error in the .NET Runtime at IP 000007FEECD9D08D (000007FEECD90000) with exit code 80131506.

I also just fixed a problem with Windows\Fonts which was causing BSOD, as described here but I doubt that's related to MCEBuddy problem https://support.mozilla.org/en-US/questions/674779

Thanks. I ran this installer and did a repair and rebooted but I'm still getting the same errors

I'd already done a sfc /scannow and chkdsk C: /F /R and they didn't show any problems, so if there's no way to check for problems and we just have to wait until a program uses each file before it tells us it's corrupt, it makes it rather hard to test a system for problems.
