XD doesn't start even after multiple restarts and re-installs of ol and new versions (even beta).

Hi there,

We are sorry for the delay in response. We would request you to please try the below steps-

1. Uninstall XD.
2. Quit Creative Cloud Desktop app and kill all related processes from Task manager.
3. Delete temp files by going to run(Win+r) then %temp%
4. Delete Adobe XD CC folder from  C:\Program Files\Common Files\Adobe
5. Restart  computer and install XD

Let us know if that helps.

Thanks,

Harshika
