This usually relates to a corrupt registry key. To correct the issue, please do the following:
1. Go to Start - Run. In the Run window, type regedit. Click OK.
2. In the Windows Registry, go to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Softwin\Bitdefender Deployment Tool\
3. The data for the Path item should point to the location of the executable (by default, this location is C:\Program Files\Softwin\Bitdefender Enterprise Manager\Bitdefender Deployment Tool\\DeploymentTool.exe). Please make sure that the data in the Path entry matches the actual location of the Deployment Tool executable. If it does not, you will need to modify the path data in the Path entry.
