    Hi Victorya,

    Thanks for asking.

    As far as I know, Teams is supported on Windows 8.1 or later. As you are using Windows 7, this is why it does not work. For more related information, you can refer to the following articles:

    Hardware requirements for Microsoft Teams

    Get clients for Microsoft Teams

    In this situation, you may need to upgrade your Windows system or use the Teams web app as a workaround. We appreciate your understanding.

    Thanks,

    Ray

    Hi Ray

    The Team desktop app worked on my Windows 7 last week, so that can't be the issue...

    Hi Victoria,

    Thanks for your follow up.

    The error says native-utils.node is not a valid Win32 application. Would you please try again to uninstall Teams and delete the Teams folder under AppData and then re-install from the following link?

    https://products.office.com/en-us/microsoft-teams/download-app

    If the issue persists, please try to upgrade to Windows 10 as Windows 7 is no longer supported.

    Thanks,

    Ray

    Hi Ray

    I bought/downloaded Windows 10, have the license key but it won't install on my PC. I keep getting the report that my current Windows 7 is not an original version (it is - I have the product key!), am forwarded to a Microsoft website for verification and then it says "this page is no longer available". 

    I'm stuck. How to proceed now to update my PC to Windows 10?

    Thanks for any guidance you might have!

    Greetings

    Victoria
