Procedure

The issue can be resolved using the following steps.

1. In IIS stop the SquaredUp DS application pool.
2. On the SquaredUp Server open the following folder:
   C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files\SquaredUp[version number]
3. Delete the folder within it which is named with a randomly generated GUID.
4. ​​Start the SquaredUp DS application pool. If you check you should see a new randomly named folder has been created as the SquaredUp DS assemblies are re-copied into the new folder.
5. Browse to SquaredUp DS. The web page should open successfully and you should be able to log in.
