Hello @Larry Axon ,
Welcome to Microsoft Q&A forum.
Please try following and let us know if you can launch VS successfully:
- Run CMD as administrator, run
DISM.exe /Online /Cleanup-image /Restorehealth
command, wait for it finishes running, runsfc /scannow
command. - Close any VS instances, manually remove VS by removing/renaming following folders:
C:\Program Files (x86)\Microsoft Visual Studio C:\Program Files\Microsoft Visual Studio %programdata%\Microsoft\visualstudio\packages %Temp% (you may need to reboot your machine before renaming this folder) C:\Users\username\AppData\Local\Microsoft\VisualStudio\17.0_XXXXXXXX
After renaming/removing above folders, try to download a new setup file, put it into the root of the C drive, for example C:\setup.exe, run it as administrator to reinstall VS. Launch VS as administrator.
- Make sure that you didn’t modify some configurations on your machine. If you changed any settings before this issue appeared, please try to reset them. Also please make sure that there’s no limitation on your machine, like permission limitations, group policy, antivirus.
Sincerely,
Tianyu
