Hi. I'm in a bit of a bind and I'm not sure how to get out of it.

I just recently built a new system and installed Windows 10 Pro 64 bit.

I have had no trouble installing some basic programs: MS Office, Steam, etc. I went today to install another game and I got an error.

I have been looking for 3 hours now for a solution and have come up against another problem. A lot of solutions ask to reinstall .NET Framework and/or also try uninstalling and reinstalling Microsoft Visual C++. The trouble is a) when trying to install a new .NET Framework I get the same error; b) I cannot uninstal MSVC++. I have 6 of them listed in programs (2012, 2013 and 2015; x64 and x86 each), but when I try to uninstall it has an error and will not do anything. I tried downloading and installing 2017 and it will not work either. I even downloaded CCleaner to try and uninstall them and no luck.

I have also run check disk and tried various other "solutions" and "best fixes".

Any ideas? Anyone? Thanks!

.NET 3.5 is a feature on Windows 10, generally if an application needs it Windows will prompt you to install it. If not, you can follow this: https://docs.microsoft.com/en-us/dotnet/framework/install/dotnet-35-windows-10

As for C++ Runtimes, they can be a mess, this guy has put together an all-in-one package that works pretty well: https://github.com/abbodi1406/vcredist/releases/

Beyond that, you can try some commands to repair Windows:
"dism /online /cleanup-image /scanhealth", that will check for corruption, if it finds any, then run: "dism /online /cleanup-image /restorehealth"
The other one would be "sfc /scannow"

The sfc /scannow found problems but I cannot understand the log. (Admitted n00b here!)

As for the other items, the .NET 3.5 Framework walkthrough did not work and that C++ package could not be installed (I get the same error in the thread title).

Who Crashed is more for crashing. My PC isn't crashing, it just isn't letting me install (or uninstall) certain programs.

I appreciate the feedback; thanks! At this point, however, having spent 10+ hours on this so far and gone through more than 3 pages of google searches with no luck, I might just as well reinstall Windows. Trouble is, I don't know what I did to mess it up and how to avoid doing that again. All I did was install Windows and update windows. I haven't installed too many other things, being a new PC and all. Just Asus Aura and Nvidia drivers.

Hmm yeah, reinstalling is the easiest option at this point. I always start with .NET and C++ as my first steps since so many things rely upon them.

And yes, the SFC log is a bit messy to read. If you search for "Repairing" that should help get you closer to the files it's attempting to repair.

Didn't install any antivirus or such?

The odds are generally pretty low, but the bluescreens you had when trying to set your memory speeds may have corrupted Windows.

There's a system restore function in Windows 10, I can just run that, so it keeps all my personal files.

I'll do what you said, and install .NET and that Visual C++ (the earlier one you linked) and give that a shot.

I use Avast (have for many years on various PCs without issue). I seem to recall this error a few years back on my older PC and it was a missing/corrupted .dll file, iirc.

If you think the BSOD might be a cause, perhaps I should then try to get my XMP/DOCP up and running and stable prior to doing the restore.

Did you have Avast installed on the install you had the error with? If so, save that until last as the most recent W10 update had issues with some third party AV.

No, Avast was the first thing I installed after Windows and that has run without issue. I basically only have installed Avast, MS Office, Steam, qBitTorrent and then drivers and Asus Aura. I tried to install a new game (Magic: the Gathering Online) and got the error.
