[#2]

did you run the executable as administrator?

[#3]

C:\Users\Admin

yes I would say so....

Run it as the user, Teams need to run in the context of a logged in user.

[#4]

that is an assumption ;)

[#5]

Yes, I tried. but its not worked.

[#6 · Accepted solution]

I just cut/Delete the Teams folder from C:\Users\Admin\AppData\Local\ and pasted it some other location and installed the Teams. its worked.

@Reddy7 

Are you installing it for multiple users and do you have a software restriction policy in place?

Is so you would simply use the variable %LOCALAPPDATA%\Teams\ to allow everything you need these below:

%LOCALAPPDATA%\Teams\

Teams.exe

%LOCALAPPDATA%\Microsoft\Teams\

%LOCALAPPDATA%\SquirrelTemp\Update.exe

teams_windows_x64.exe

Hey @Reddy7 ,

I have been looking for a solution to this problem and I've tried almost every possible solution available on the internet from deleting the folders to clearing registries etc. 

The only resolution I found was to copy these three folders Teams, TeamsMeetingAddin and TeamsPresenceAddin from someone who has a working Teams Desktop application (in my case I needed it from a Windows user) and paste it in the given location. C:\Users\<user>\AppData\Local\Microsoft. 
I tried this solution because I saw an error related to this location in my SquirrelSetup logs. 
Although this is a very old post but perhaps this can help someone like me who is looking for a solution. :)

I ran into the same issue.  I simply deleted that %LOCALAPPDATA%\SquirrelTemp.  Ran the Teams installation and it recreated that folder and then completed as expected.

The best answer is uninstall teams setup in your  PC and then delete it from your computer.... Next, download another teams setup and install it...     IT WORKED...100%
