Server Version#: 1.20.1.3252 Player Version#: 2.58.0 PC Windows 10 Good Morning, I have just updated to PMS latest version \*\* and at the same time had a Windows update install during the restart. When i have turned my PC back on i get the following message. ‘The application was unable to start correctly (oxc0000022)’ ![image](https://global.discourse-cdn.com/plex/original/3X/4/2/420f344e3c22cf1374b9c07f6b9b630fe518604c.png) I have tried to uninstall/modify PMS via windows but i get the following error ’ The installer has insufficient privileges to modify this file: C:Program Files Plex\Plex Media Server\boost\_thread.dll. ![image](https://global.discourse-cdn.com/plex/original/3X/a/f/afd2a1f8941b132fe5a8fb615c0f2447bc4e534d.png) I have tried to uninstall the windows update, tried to run PMS as an admin whist trying to modify and uninstall, restarted my PC and now i am out of ideas.

It was my antivirus software which was causing the issue. I uninstalled it which fixed my issue. ---

wow interesting. I tried that and it didnt work. What I had to do to fix mine just now was remove plex from my startup programs, restart, uninstall, restart, and then reinstall vers. 1.18. Whenever i tried to install the latest update (1.20) the same problem would keep reoccurring even after I uninstalled bitdefender. ---

Pleased you managed to get up and running again 😀. I’m not even subscribed to bit defender anymore I didn’t think it would still be running to block things. ---
