You open the Lansweeper web console, and you see an error “ The given key is not present in the Directory”


Now what? 

The error The given key was not present in the dictionary is rather generic and can have multiple causes.

  • To ensure the issue is not caused by an incorrect, corrupt or missing website file, we recommend clearing the ASP.NET cache, which may already resolve the issue.
  • Stop your webserver service. Your webserver service is either World Wide Web Publishing Service (IIS) or IIS Express.
  • Empty the folders listed below.
    • C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
    • C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319\Temporary ASP.NET Files
  • Restart the webserver service
  • Test the web console

Not fixed?

If the issue persists, there may be an issue with the page itself.  We would recommend reinstalling the web console.
