So trying to update to a newer version of PCAmerica I get this random error. It has taken me a little time to write this but I believe I was trying to update somewhere around the 12.6xx to a 12.7xx .
If I run into this error again I hope to give you an exact version that gave me the problem but the fix was to update the .NET Framework. I think I updated to 4.6.2 and that fixed the problem.
So if you get this error don’t sweat it. Easy fix.
