Hi,GorbGorb-3459
You can try to open the 'services.msc ' (Win+R) , and close the 'Windows Update'.
Then type 'net stop WuAUServ' in cmd to close Update Service.
Find the 'SoftwareDistribution' folder in 'C:\Windows' and rename it as 'SDold'.
Finally restart the update, uninstall the .net framework and install it again.
Best Regards,
Jerry Cai
