In the 'Options' dialog, turn off the fast launcher and you can start more than one Sybase Central.

You shouldn't have any problem running different major versions against the same database - I do that quite often. Just make sure that you explicitly specify the paths of any utilities you want to run - don't rely on the PATH to find them.
What problems are you seeing?
Running different minor versions (ie different builds of the same version) is rather more tricky - I'm not sure how easy that is - unless you do a manual install of the necessary files.
