Having trouble trying to fix Microsoft Teams’ installation issues?
New users of Microsoft Teams will find themselves greeted by a lot of great productivity features. The Microsoft program offers a ton of versatility and accessibility. For one, it supports a lot of media types that otherwise wouldn’t pass off in other chat-based collaboration applications.
Microsoft Teams are often used extensively by schools, startups, and even big companies. However, an uncommon but greatly affecting issue that can put you off from trying out the Microsoft service is running into installation issues.
In this article, we’ll be figuring out why you’re having this problem and guide you through the steps to help you fix it. Here’s how you can fix Microsoft Teams installation issues.
Let’s get started!
- 1. Uninstall Microsoft Teams Completely.
- 2. Remove Microsoft Teams’ Cache Files.
- 3. Run The Installer As Administrator.
- 4. Use The Registry Editor.
1. Uninstall Microsoft Teams Completely.
If you’re trying to reinstall Microsoft Teams, an installation error might be the result of a currently existing Microsoft Teams app on your computer. Getting rid of programs can be a complicated process if you’re either new to Windows 10 or are unfamiliar with the uninstallation process.
Similarly, this problem can also affect Mac users. In cases like this, uninstalling a program by simply deleting them can cause file residues. These will eventually hinder any other installations as your operating system might consider Microsoft Teams as already installed.
In further methods, we’ll be clearing other files, but for now, we’ll uninstall Microsoft Teams properly.
Here’s how you can uninstall Microsoft Teams for Windows:
- First, open up the Start menu and type in ‘Add or remove programs’. Select the first result in your search query.
- Now, you should be directed to a window with a list of all currently installed programs on your computer. Under Apps & Features, utilize the search bar and type in ‘Microsoft Teams’.
- Finally, click on the program and select Uninstall. Follow the prompts to finish the process.
Alternatively, here’s how you can uninstall Microsoft Teams for Mac users:
- Before you proceed, make sure that Microsoft Teams is closed and not running in the background. You can check by using the Activity Monitor and searching for Microsoft Teams.
- Now, open up Finder and go to the Applications folder.
- When you’re there, try to locate Microsoft Teams and drag the application to the Trash. This will uninstall the program.
Just because you aren’t finding Microsoft Teams in the steps above doesn’t mean that all related files have been deleted. Go ahead and move on to the methods below to delete Microsoft Teams’ cache files.
2. Remove Microsoft Teams’ Cache Files.
Cache files are incredibly useful assets that help improve the user experience for your application. Even for websites, cache files are often saved and collected in the form of cookies.
These data files will take note of any changes or settings you’ve set, and upon reopening that program or website, will load your preferences and replace the default settings. This essentially makes sure that any personal changes you make to the programs you visit and use are kept and saved.
Microsoft Teams keeps a record of your cache files somewhere on your computer. If the program was uninstalled incorrectly, the cache files may have been left behind which could be the cause of the installation error.
Here’s how you can remove Microsoft Teams’ cache files:
- We’ll need to open up the Run dialog box to locate the cache files. Open this by pressing the hotkey Windows key + R or by searching for ‘Run’ in the Start menu.
- With the dialog box open, type in ‘%appdata%’ and press Enter.
- A list of numerous folders should be displayed on your screen. Look for and click on Microsoft.
- Once you’re there, locate and delete the Teams folder. You can do this by clicking on the folder and pressing the Delete key to move the file to your Recycle Bin. Similarly, you can also permanently delete files by pressing Shift + Delete.
Try to install the program again to see if that fixed your Microsoft Teams installation issue.
3. Run The Installer As Administrator.
‘Administrator Mode’ is a powerful tool that usually overrides most errors. Running most programs ‘as administrator’ gives it a higher level of access to your computer. For installers, this can be the difference between installing your app or not.
This is generally not recommended, however, you can trust Microsoft Teams since it is developed by Microsoft. Most installers shouldn’t need to be run as an admin, but doing so will bypass a ton of complications that could be caused by your anti-virus and firewall.
Here’s how you can run the installer as an administrator:
- First, go to Microsoft’s website and download Microsoft Teams.
- Now, open the Downloads folder or the folder the installer is saved in. Depending on your browser, you can also just view the downloaded file and click Show in folder.
- Finally, with the installer file on your screen, right-click the installer and select Run as administrator. You will be asked to confirm or even input the admin credentials on your system. Fill this in and continue.
Any issues with permissions or anti-virus protection should now be bypassed by the Microsoft Teams installer. Hopefully, that has solved your Microsoft Teams’ installation issue.
4. Use The Registry Editor.
The Registry Editor is a powerful collection of all level-one settings that you can configure on the Windows operating system. Your systems settings are collected and displayed in the editor, where we can easily access and configure these files.
In this method, we’ll be modifying a file that could be uninstalling or preventing the installation of Microsoft Teams. This is particularly for users that can install Microsoft Teams but find that it gets deleted or uninstalled after a couple of hours.
Here’s how you can configure the Registry Editor:
- Start with opening up the Start menu by pressing on the Windows key.
- Now, type in ‘Registry Editor’ or ‘Regedit’ and click on the first result from your search query.
- On the left side panel, navigate through the folders until you reach the Teams folder. Here are the folders to open:
- On the Teams folder, you should notice a file named PreventInstallationFromMsi. Double-click on this file and change the Value data to 1.
- If you cannot find the file, simply right-click on an empty space in the folder and hover over New then select String Value. Name the new file as ‘PreventInstallationFromMsi’ and set the Value data to 1.
Try and install Microsoft Teams normally or by running the installer as an administrator. This should fix your issue and stop it from uninstalling on its own. Feel free to check out our other article so you can disable Microsoft Teams opening on startup.
