I have vista on my computer where abouts can I find a patch so that it will work on my computer

Well, this is one of the problems of upgrading to vista..

I don't know how well supported entropia is nowadays, I know it's fairly old.

You'll be better off asking the devs at
Entropia Universe (http://www.entropiauniverse.com/)
Or
M I N D A R K | P E (http://www.mindark.com/)

Good luck!

I was able to get it working on my Vista PC. I only replaced the .dll file that Entropia said it couldn't find. I put that .dll file into the C:\windows\system or system32 directory. The only problem is that my Entropia crashes when I die... I can't figure out that problem yet.
