oops a wrong link
I gues you woul need to delete the registry Perform the steos as below

Following is the command to uninstall the AOFO
setup.exe /AOFO: -s -u, and press <Enter>

Manually remove the Backup Exec VSS provider registry key

(1) Find the correct GUID value for the Backup Exec VSS provider by running the VSSADMIN LIST PROVIDERS from within a command prompt window.

(2) Run regedit and go to the following key location:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\VSS\Providers\

(3) Delete the registry key with the coresponding VSS GUID value

(4) Reinstall the remote agent without AOFO option.

Thanks RahulG,

I checked ja deleted that registry entry, it seems that i need to reboot the server before BeVssProvider service gets removed from Windows services list.

BTW, i didn't install BE Agent with AOFO, BeVssProvider seems to install with basic BE 2010 agent, but there's something missing from Symantec's BE Agent unistallation method...

Hi JT

Hi Amol,

I found that article too, but unfortunately it's not applicable for BE 2010 agent removal/uninstallation.

Its just because of some environmental reasons the uninstall does not works fine so we need to uninstall it manually ..
