Try to use the recovery in the installer. In the Add/delete program, it is called Microsoft. NET Framework Version 2.0, XP has not been used for a long time. I guess it is correct. It should be in the update of successful installation. If the installation information is still there, you can use an MSI clearing tool, if it does exist. delete the msi of net2.0 and reinstall it. In addition, you can search for this error number in the search box on the Microsoft homepage based on the error code to find a solution.
