Sony Vegas is crashing the moment I press render regardless the format chosen on a freshly installed Windows 8.1.

I ran sfc /scannow and Windows Updates but no errors were found.

Luckyly I found a solution in this thread (Vegas closes upon any attempt to render): Clr.dll in Net Framework 4.5 causes Vegas to crash, this hotfix claims to fix it. However this hotfix is only applicable to Net Framework 4.0, and Windows 8.1 comes bundled with 4.5.

Net Framework repair tool won't provide a repair option:

And attempting to repair Net Framework using this command fails to work:

DISM /Online /Cleanup-Image /RestoreHealth

What else can I do to fix this?

    The hotfix you linked to is for .NET Framework 4.0 applications. Windows 8.1 has .NET Framework 4.5.x by default which is an in-place replacement for .NET Framework 4.0.x, in otherwise the hotfix does not apply to your operating system. Due to the age of the hotfix I would be shocked if it had not already been rolled into a later version of .NET Framework 4.0 anyways

  • Thanks for clarifying, I will deviate the question from the hotfix.

  • Even if you were running Windows 7 with .NET Framework 4.0.x installed based on the problem signature and the signature described in the support article, they are not even close, the exception offset isn't even the same. I assume you have install all available updates?

  • You will need to use the DISM tool against a Windows 8.1 installation since your WinSxS directory appears to be empty. Your WinSxS source directory not existing is a separate problem you should solve.

  • WinSxS has many folders and is 6.63 GBs large. Do you suggest to replace this folder with a WinSxS copy from another Windows 8.1 installation?

I installed Microsoft .NET Framework 4.6 RC (DP46-KB3006563-x86-x64-AllOS-ENU.exe) and the error is gone!
