Upgrading DPM 2010UR5 Agent to DPM2012R2UR1 Agent

Question

Hi all,
we are running DPM 2010UR5 Protection Agent on a Win2008R2 Server with Exchange 2010.
I have to upgrade the Agent in order to move backups to DPM 2012R2 UR1.Previously I wanted to uninstall the old Agent .
Unfortunately there is no option in Control Center/Software to uninstall the Agent - it is just listed under Updates.
Because of that I tried:
"Msiexec /x {72BF00D8-53E0-1539-F523-4347082BCC11}" an
"Msiexec /x {72BF00D8-53E0-1539-F523-4347082BCC11} /qn /REBOOT=ReallySupress"
But i did not work either.
So, what would be a good way to upgrade DPM 2010UR5 Agent to DPM 2012R2 UR1 Agent?
Thanks in advane
regards

Can you try something like this?
$reg = Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*" | ? {$_.DisplayName -ne $null -and $_.DisplayName -like "*DPM Protection Agent*"}
if ($reg -ne $null)
 $pkey = $reg.PSChildName
 cmd.exe /q /c "start /wait msiexec /x $pkey /quiet"
Thanks.
BTW, how can you determine that the agent is still installed when you can't see it on "Add/Remove programs" window?
