Solved: Re: Power BI desktop won't start - Microsoft Power BI Community
Suggested troubleshooting method should be the following (we may directly go with those steps without checking the logs):If you have any system backup, then use it to restore back the health status, and do the update again;If there is no backup available, open CMD with admin rights, run the following command: Dism /online /cleanup-image /restorehealthAfter doing step 2, check your Microsoft SQL server status, if still in trouble, try to perform a repair. (Reference)If there is still performance counter errors, run the lodctr /R command after step 3.See if the above would helps.Regards
