At one time last year I had no problem installing & running the Microsoft Teams desktop app on my Windows 7 64-bit laptop. After a period of time the program would no longer run. So I tried to uninstall & reinstall but nothing works. The installer runs but then stops without launching the program. I see a desktop shortcut which, when clicked on, does literally nothing. I tried pasting the shortcut target (C:\Users\mwahle\AppData\Local\Microsoft\Teams\Update.exe --processStart "Teams.exe") in the command window, but all that happens is a brief flash of a dialog and that's it. I looked in the SquirrelSetup.log file and see this message:

 

2018-04-04 09:50:23> Program: Starting Squirrel Updater: --processStart Teams.exe
2018-04-04 09:50:23> Program: Want to launch 'C:\Users\mwahle\AppData\Local\Microsoft\Teams\current\Teams.exe'
2018-04-04 09:50:23> Program: File C:\Users\mwahle\AppData\Local\Microsoft\Teams\current\Teams.exe doesn't exist in current release
2018-04-04 09:50:23> Unhandled exception: System.ArgumentException: Value does not fall within the expected range.
at Squirrel.Update.Program.ProcessStart(String exeName, String arguments, Boolean shouldWait)
at Squirrel.Update.Program.executeCommandLine(String[] args)
at Squirrel.Update.Program.main(String[] args)

 

I checked the "current" folder and while there are many files, the only executable present is Squirrel.exe. There is no file named "Teams.exe".

 

Help?

Delete the folder C:\Users\username\AppData\Local\Microsoft\Teams

Then download the latest version and try installing again from https://teams.microsoft.com/download

Christopher,

 

I had already tried that approach previously, even shutting down & rebooting between deleting that folder and reinstalling, but it did not work. I tried it again after reading your reply, just in case something went wrong the first time I did it, but still nothing. I am really curious as to why I do not see a Teams.exe file in the "current" folder as that is what it appears is needed...

you must have some kind of AV software deleting it or something only thing i can figure would be causing it.

I've got the same or a similar problem. the Teams app was running, and now I get an error message when I try and run the executable. I get a Win10 error dialog stating 'This app can't run on your PC'.

 

The issue extends to the browser version as well. It starts loading, then I get a 'D'oh something went wrong error' flashed up briefly, and then it throws me back to the dialog asking me to select an account. I pick the relevant account and the cycle repeats.

 

Uninstalling Teams I get the Windows error message stating 'This app can't run on this PC'.

 

Any clues?

Well thank you very much for this simple solution!!  I was growing increasingly frustrated trying to find issues to resolve the javascript error that accompanies the install fail.

I am having a similar issue.  I have never used Teams.  When I attempted to install it places the icon on the desktop.  I attempt to launch it and it never opens.  The icon on the desktop changes to a piece of paper.  Nothing will ever open. I have removed the folder mention and downloaded it again but same result.  Please help.

I can resolve the issue by re-running the downloaded installation program as an administrator...BUT

 

The BUT is about a couple of issues:

* After happily running Teams for some time, unpredictably I get the 'Can't run...' error message again

* Sometimes (but not all the time) I can't re-run the Teams installer under my own user ID - and I am an administrator. Using Run As Administrator works every time and solves the problem...

* ...BUT I keep having the same problem repeatedly. I might be working for a month or two quite happily, and then have the app can't run error again. I checked to see if the EXE update date was set, indicating a new release, but this was not the case

@Mark Wahle 

After searching a lot on the internet and reading the log of SquirrelTelemetry, we need to remove the PreventInstallationFromMsi entry in the registry :

HKEY_CURRENT_USER\Software\Microsoft\Office\Teams

 

Then you can install again Teams

Restart and it's working.

 

Hurrah!

@Mark Wahle  hello  i am seeing that many people are facing this problem and i was one of them just before replying. I tried many methods and tricks that i found on google, also changed the coding but none of them worked .

this was the method that worked for me-

1. restart your computer.

2. cut the downloaded app from c folder and paste it on desktop.

3. right click and click on run as administrator.

4. when it asks for permissions click yes.

5.then click on the application it will install successfully

 

I hope my article may help you :)
