So, I've been trying a lot of things to get my computer to run a few programs that depend on C++ and the .NET framework. I tried to reinstall the .NET framework, but it failed, with the error message

catastrophic failure (0x8000FFFF)

Soon after, I realized that Windows was not updating at all; I tried a LOT to get it to update, but usually wound up with the same error code (0x8007007e).

I attempted a LOT of troubleshooting steps, but none of these seemed to help. My Windows Update log file is here.

I've tried to run sfc in safemode, and manually enabled trustedinstaller, but it still did not work, giving me the same error. I've also tried running DISM.exe, it loads to 100%, then gives me a message that says an error occurred and no changes were made.

PS: I would like to avoid reinstalling windows or any hardware changes at all costs.

  • Are you positive that the program requires both the Visual C++ Redistribution 20xx and .Net Framework? – Ramhound Jan 27 '18 at 16:44
  • I don't know, but there's still the issue of windows not updating and sfc or dism working. – MazeOfEncryption Jan 27 '18 at 16:46
  • And it is probably 2 different programs, one depending on .net, the other depending on c++. – MazeOfEncryption Jan 27 '18 at 16:47

If you have a windows iso file just mount it and with the help of dism tool you can add .net framework without any errors.. just google on how to install windows features with an iso

  • That's not my only issue... windows won't update either. – MazeOfEncryption Jan 27 '18 at 16:58
  • What error code do you get for windows update. Is it same as mentioned earlier – shravan sharma Jan 27 '18 at 17:00
  • Yes. 0x8007007e – MazeOfEncryption Jan 27 '18 at 17:36
  • I also had this error some days back with a cumulative update in windows. All i did was an implace upgrade as even microsoft chat support also wansnt helpful – shravan sharma Jan 27 '18 at 20:12
  • How might I do this? Just a quick google search gives me an application to create an ISO to install windows. Wouldn't this destroy all of my files? – MazeOfEncryption Jan 27 '18 at 21:47
