    This is quite late to the party but when I encountered this issue it was comorbid with some other runtime errors on other applications. In my instance, the culprit was a failed/broken installation of the Visual Studio C++ Redistributables. I resolved by finding the VC+ redists in Apps & Features and running the built-in repair on them. Was able to get rid of error without a reboot. Hopefully this helps someone else who runs into the issue

    We got the same issue on 5 computers out 250, just this morning, really strange that it occurs on several PC:s at the same time. On one of them I just deleted all files in the C:\Users\username\AppData\Local\Microsoft\Teams folder, rebooted and started Teams again and it was solved. Happily moved on to the next machine, but after the reboot it couldnt find the Teams.exe file!?! I downloaded the installation file from https://www.microsoft.com/sv-se/microsoft-teams/download-app but got the same error message when starting the installation. Great....

    Maybe it was too brutal to just wipe the files in the Teams folder, I will try to uninstall Teams on a third machine tomorrow, then deleting whatever is left in the Teams folder, and then reinstall.

    Thanks Mathias.

    I agree with you that this is really strange because this is no known changes were made to the machine at least in my case.

    Initially, I made an attempt to uninstall Teams, got the same error message, and the uninstall process was aborted.

    Then I renamed the folder (practically deleted the folder as you did) and ran into the same problems as you had experienced.

    To uninstall Teams, I copied the content of the folder from another computer that had an older version of Teams. Then I was able to uninstall Teams successfully (I think).

    I will try to find a different installer to install Teams sometime this afternoon and post what I find here.

    Thanks Igor Araújo.

    Before posting the question, I found the same thread and tried all of the suggestions including reinstalling Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019, x64. However, I still have the same issue. Do you have any other suggestions?

    Thanks again!
