Please delete all the entries of previous veritas backup exec version 9.0 or 9.1.Once reboot the server.
Before installing version 9.1,rename the old bkupinst.log file to bkupinst.old. So that new bkupinst.log file will generate for backup exec version 9.1 installation.
(You can find this File under WINNT folder)
If you can not install 9.1 even after this please paste the exact error message from this new bkupinst.log file. For this :
1.Open the bkupinst.log File
2.press Ctrl+f key and fine for this error : "return code 3"
3.Please paste the first exact error
For any further queries please revert.
Thank you.
