[#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.
