A CLR error on your computer is a serious error that can prevent your computer from booting properly and many applications from working. One of the most common CLR errors is “CLR Error 80004005”, which occurs on Windows systems during the boot process.
This error is usually caused by more than one .NET framework being installed on the system at the same time. Although two or more .NET frameworks can run simultaneously on a system, some of them have compatibility issues. To fix the CLR error, you must remove and properly install multiple frameworks.
