Sorry if this sounds like a really dumb question, but I'm new to this, lol.

Ok, I downloaded Theme Hospital, and the file type was .iso

Whenever I go to open the file, it automatically opens the program I use to write CDs.  So, i burnt the file onto a CD and whenever I try to access it from the CD it still opens up my burning program...

Any ideas on what I'm doing wrong? Or is there something else I should be doing?

Thanks in advance for any help
