Support Session Cannot Start - Expired Session

The end-user may not be able to start an Ad Hoc support session.


When starting an Ad Hoc support session, the customer (end-user) sees the following message:

Support Session Cannot Start. This instance of Support Session has expired. Please tell your support provider about this message.



  • Ask the user to click the activation link in the most recent email you sent
  • Create a new ad hoc support session

Second, if the problem persists:

  • On the computer to be controlled (the end-user's computer), the registry key for LogMeIn Central must be deleted at this location: HKEY_LOCAL_MACHINE > Software > Classes > Installer > Products
Important: Use care when modifying the Registry. If you are not familiar with the Windows Registry please contact Customer Support for assistance.
