Cause

The BlackBerry MDS Connection Service is terminating unexpectedly because it is unable to successfully start Java®. The Java failure is caused by the BlackBerry MDS Connection Service ImagePath is pointing to the incorrect version of the jvm.dll file.

  1. Click Start > Run.
  2. Type regedit and click OK. The Registry Editor appears.
  3. Edit the following Value data string as follows: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\BlackBerry MDS Connection Service\ImagePath
