Hello!

If you get the following error regarding the impersonation – it could be the problem with wrong registered Machine Debug Manager:

[center]

It means that we have installed the mdm (Machine Debug Manager) from VS2002 (which is not used anymore). To fix it we should perform the following steps:

1. Disable MDM service
   [li]Open system services window: click “Start” -> then type “services” and select it (or find this console via “Control Panel” -> “Administrative Tools”):
   [center]
   
2. Click right mouse click on ” Machine Debug Manager” and open “Properties”
3. Stop the service (click the stop button) and disable it (change the status Type)

   [center]
   

[/li]

4. Reregister system DCOM MDM
   [li]Open cmd as an Administrator: click “Start” -> type “cmd” -> right mouse click -> “Run As Administrator”
5. Register the server:
   [ul]
   [li]WIN 32 (x86): type the command:
   [ul]
   [li]mdm.exe /regserver
   [center]
   

[/li]

6. WIN 64 (x64): type the following (we have to change the directory to SysWOW64):
   [li]cd ..SysWOW64
7. mdm.exe /regserver
   [center]
   

[/li]
[/ul]

[/li]

8. Restart the computer.

[/ul]

[/li]

9. Work with ZAPTEST. If you get access issues, please check DCOM permissions (Run -> “dcomcnfg” -> Find “Machine Debug Manager”)
   [li]Go to: “Component Services” -> “Computers” -> “My Computer” -> “DCOM Config” -> “Machine Debug Manager”
10. Right mouse click -> select “Properties”

    [center]
    

11. Open “Security” tab and recheck permissions. Try to add everyone to understand that it’s a permission issue.

Thank you,
