I would imagine it should be fine installing it afterwards.. It should just
dump various "*.lic" files into the TSM server directory. The license files
are only available off the base cd.. i.e. 5.1.0, or 4.2.0, or whichever
version you have. If you download an update like 5.1.1, it doesn't include
the license files. That's why when you do a fresh install you always start
with the base level off the cd, then upgrade it with the update. So you get
the license files installed.

I'd first check if there are *.lic files in the directory and try licensing
it with the command below. If that doesn't work it probably wasn't
installed. If that doesn't work then next I would halt the TSM server (type
halt at TSM admin prompt or if you're using windows, stop the TSM server
service), install the license files, and then start the TSM server again (in
windows, the TSM server service). Then try registering it as below.

IF you're uncomfortable doing it you could always call Tivoli support and
have them walk you through it but it's pretty painless. Doubt you'd hurt
anything as TSM is pretty resilient.
