I am having all kinds of problems when trying to load Arcserve 11.1 sp 2 on one of my servers.

A little back ground on the issue:

I had to reinstall Arcserve on my Netware 6.5 SP8 server, so I deleted the Arcserve folder from the SYS volume. I forgot to delete the Arcserve objects out of C1, so I deleted the objects out of C1, then deleted the Arcserve folder from Sys Volume.
I tried to reinstall Arcserve and I am getting the following error everytime I try to reinstall.

A fatal error has occured. This program with terminate. You may check C:\Program Files\Common Files\Novell\ni\data\ni.log for more details after you dismiss this dialog.

Any help with this issue would be greatly appreciated!!!
