I decided i want to play Morrowind again i've tried to install but after i do nothing happens! What should i do? Is something wrong with my computer?

We're going to need more info.
"Nothing happens" tells us exactly nothing.

When does "nothing" happen. During install? During start-up? When you start a new game?
If you get any errors, what are they?
Which OS are you on?

Sorry got a little ahead of myself. I'm on xp, and after when i have clicked on yes if you want to install the game nothing happens.
I get no errors what so ever.
