    Hello! I have a problem concerning a project where I installed a new version to work with it, specifically 2019.2.0f. When I opened it for the first time, it worked. It was late at the time, so I turned it off and went to sleep. When I turned it on again the next day, it gave me the error in the attached picture.

    I've already tried uninstalling and reinstalling Hub, but it simply yielded the same error. How do I fix this?

    please post a screenshot of your installs tab so we can see if the versions are installed properly?

    This is the best way to use Unity 2019 from my today attempted.

    1.) Uninstall all Unity Editor versions that not need / Can't open
    2.) Uninstall Unity Hub
    3.) Delete all folders contain words 'Unity' on 'C:\Program Files'
    4.) Delete all folders contain words 'Unity' on 'C:\ProgramData'
    5.) Delete all folders contain words 'Unity' on 'C:\Users\YOUR_ACCOUNT_NAME\AppData\Local'
    6.) Delete all folders contain words 'Unity' on 'C:\Users\YOUR_ACCOUNT_NAME\AppData\LocalLow'
    7.) Delete all folders contain words 'Unity' on 'C:\Users\YOUR_ACCOUNT_NAME\AppData\Roaming'
    8.) Press 'Windows + R' >> Type 'regedit' >> Go to 'Computer\HKEY_CURRENT_USER\SOFTWARE' and delete all folders contain words 'Unity'
    9.) Download newest Unity Hub (Not beta)
    10.) Download Unity 2019.3.15f1 or Unity 2019.4.5f1
    11.) Install Unity Hub >> Login >> Apply Personal License
    12.) Install Unity 2019.3.15f1 or 2019.4.5f1

    Now you can open project by Unity Hub XD.

    Hope this help.

    Hi @rexthebuizel
    Based on your first screenshot, it looks there is no Editor shown under the Unity Version column. Have you tried clicking the 'down arrow' in that column and selecting an Editor you already have installed?
