Key not Present in the Dictionary

After upgrading, Remote Desktop Manager gives the error message: The given key was not present in the dictionary.



This is a Microsoft bug, but there is a workaround.

  1. In Remote Desktop Manager go to File - Data Sources
  2. Select your data source.
  3. Click Edit - Advanced - More Settings
  4. In the Failover Partner Value field, type one or more space.
  5. Click OK
