OSS Reinstall Service on Vista

When I installed Disk Director on Vista, even though I was careful not to install or activate OS Selector, I still ended up with the "Acronis OS Selector Reinstall Service" as a registered service in the list of Vista services.

I've disabled the service but each time that I reboot the machine I get an error message in the Event Viewer "The COM+ Event System could not remove the EventSystem.EventSubscription object {44762824-7786-43D0-BB16-BD1F595F2BDE}-
{00000000-0000-0000-0000-000000000000}-{00000000-0000-0000-0000-000000000000}. The HRESULT was 80070005".

Usually to unregister a service you would enter at an elevated command prompt:

Code:

regsvr32 /u {path to and name of service}

I tried this with the file C:\Program Files\Common Files\Acronis\Acronis Disk Director\oss_reinstall_svc.exe but the command expects a dll as an argument; not an exe, so it fails. Is there any way to unregister the OSS reinstall service?

 

I've tried this on my Vista test computer. I can disable the Acronis OS Selector Reinstall Service and I got no error message upon rebooting. After it was disabled, it shows the status as Stopped in the Task Manager, but as Disabled in Services.


Deleting the following keys from the registry removed the service and the computer started and ran normally without the service.

Code:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\AcronisOSSReinstallSvc

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\AcronisOSSReinstallSvc

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AcronisOSSReinstallSvc

If you do this, you might want to do a backup before or export the registry keys in case you need to import them.

In XP, this service does not get installed. At least I couldn't find it in the list of services. It's probably something to let OSS work better with Vista.

I suppose I could have tried a little harder to track that one down! Thank you for taking the time to find it and do an experiment for me.

On my machine the three keys were in \...\CurrentControlSet\...\, \...\ControlSet001\...\, and \...\ControlSet003\...\.

I deleted them, rebooted the machine and the Acronis OS Selector Reinstall Service is gone and the Com+ Event System error on reboot is gone. Excellent!

For registry tweaks like this I always write up a short description of what I've done and why I've done it, put it in a notepad .txt file and put the file and the exported .reg keys in the program's directory, in this case C:\Program Files\Acronis\Acronis Disk Director\. Then I can always undo the change if it later causes an unexpected side effect.

Thanks as always for your help. I'm slowly whacking away at the Vista event log errors. My machine's Reliability Index finally made it to a perfect 10.0 on June 4 and has been there ever since. Vista seems to be working pretty well for me.
