How to reinstall Backup Exec Remote Agent on remote server

[142a]

I accidentally removed(using Add/Remove Programs)the remote Agent from remote server. Now I need to re-install it from Veritas Backup Server. When I do so, it always popup a window with error message:
---
Install has detected the priviously install version(s) of which is not supported for this upgrade(see

http://seer.support.veritas.com/docs/252928.htm)

---
and doesn't allow me to do remote installation.
Actually I have only one version (Veritas Backup Exec 9.0 for Windows Server).
Any help would be appreciated. Thanks in advance.

You might be using an old activation number for an older version of veritas. Try entering another activation number for ver 9.1

You might want to download the free backup exec v9.1 upgrade at the following address as v9.0 is a bit flaky

oaklandadmin and shady,
Thanks for responding my question. I'll try your suggestions. I'm new in doing backup and have a lot of questions.
