Back up your files!

It is important to have all the time at least two copies of all files in separate locations. Always before any installations or changes on the computer it is best to prepare for the worst, i.e., that the computer becomes unusable. Even though the risk is small, you should make sure before the installation that you have copies of all your files e.g., on in your Z drive. Using the local hard drive (C:\) of the computer as a permanent storage is not recommended, anyway. Read more about saving files and making backups safely.

Choose the installation time

You should not start the installation on a busy workday morning. Choose a day when you do not need your computer the whole day. We recommend that you schedule the installation for an evening. The computer completes the installation after you have started it as instructed.

If Microsoft Teams disappears

It is possible that Microsoft Teams disappears from your computer during the installation. If it happens, you can get Teams back to your computer as follows:

  1. In Windows resource browser, open folder C:\Program Files (x86)\Teams Installer.
  2. 2.Double-click the Teams.exe file in the folder.


  3. If there is no Teams.exe file in the folder, you can reinstall Teams as follows:

    1. Open Software Center (in the Start menu).
    2. Select Teams 1.4.1 Machine-Wide Installer.
