# Troubleshooting
# Microsoft Teams or other app won't install
The Squirrel installer has a bug (opens new window) where it can confuse itself with stale data. You may see Microsoft Teams by Hype Performance Group.
Resolution:
- Open
%LocalAppData%\SquirrelTemp
in the File Explorer address bar. - Delete
SquirrleTemp
folder. - Attempt installation again (of Hype Operations Center or another Squirrel installer).
