NBU service on this box are running on user ID who is in administrators group on this box. When I did login to this box, created the silentinstall.resp file as in above logs and ran the same command it went on fine?
"C:\Program Files\Veritas\NetBackup\Temp\nbclient_8.1.2_windows_x64.sja.extracted\setup.exe" /CLIENT -s /REALLYLOCAL /RESPFILE:'silentinstall.resp'
So why this could not finish successfully when started by deployment policy?! interesting... In the event log on this system I did not find anything interesting, only this:
EVENTID 1042
Ending a Windows Installer transaction: C:\Program Files\Veritas\NetBackup\Temp\nbclient_8.1.2_windows_x64.sja.extracted\\Veritas NetBackup Client.msi. Client Process Id: 11092.
EVENTID 11708
Product: Veritas NetBackup Client -- Installation operation failed.
EVENTID 10001
Windows Installer installed the product. Product Name: Veritas NetBackup Client. Product Version: 8.1.2. Product Language: 1033. Manufacturer: Veritas Technologies LLC. Installation success or error status: 0.
In that user ID %temp% folder I did find some MSIxxx.log with return value 3 inside... but no clue what is the culrpit...
I am attaching for those who can read it better to this thread...
