It could be that only the installer has issues. If you're dual booting have you tried launching the already installed program from your windows partition?
Otherwise I would try launching the installer from the wine command line to see if it gives you a specific error there.
Don't think I necessarily believe things or don't believe them based on one assertion by someone. I am able to hold it in my mind with a certain confidence level attached. Of course that doesn't really answer your question, only kicks it to "how do you form that confidence level?"
Have you considered casting zone of truth?
