Microsoft Teams failed to extract installer – Workaround

Background.

The Microsoft Teams Client fails to install on Windows 10 with the error message Installation has failed, Failed to extract installer.

A bit of searching on the internet reveals this seems to be a fairly common issue but no fix has been provided. Now I tried the same client on Windows 7, it worked absolutely fine, on Windows 10, computer says no.

The workaround.

I am not calling this a fix as although this will get Teams working, it will not appear in the list of installed applications, and you will not be able to take advantage of the silent install switch.

To perform this workaround, I grabbed a copy of 7ZIP Portable which is available here.

Open 7ZIP and browse to the location the Team’s client has been downloaded to. Highlight the file and click extract. Make note of the extracted folder location.

Now browse to the extracted folder within 7ZIP and locate the *.nupkg file as shown below. Perform the same extract operation as before.

Now browse to the folder the *.nupkg file was extracted to and copy all the contents

Now navigate to the hidden appdata folder in the user account folder. In my example, the folder path is c:\users\ian.sanderson\appdata\local\microsoft. You will need to either show hidden files or type the path to appdata n the address bar. Create a new folder called Teams. This is the standard installation location for the Teams client.

And voila, run the Teams application.

Create a shortcut to the app so it is easier to access in future.
