Strugling with this error for months now. Windows 10 Pro. Already uninstalled .NET 3.5 and reinstalled it. Removed scheduler dll's. Downloaded fresh PatchMyPC version. Ran SFC /SCANNOW. Nothing helps so far. System is up to date with all Windows updates.

At startup of PatchMyPC this error appears:

We will look into this, but it's likely a machine specific issue.

We've recently updated Patch My PC to no longer require .NET 3.5. Follow the directions at https://patchmypc.net/download for the config file.
