The software that I’ll definitively not recommend you. The question is why? Because:
- With version 3 and 4, I were not able to use it easily with my bootcamp partition (see here).
- The support was with version 3 non existant (an email posted on 8 july 2007 is still unanswered) and with version 4 still have no clue, after more than 6 months of availability, of basic problems.
- The company does not seems to improve its product but to add as much as possible features even if still in “beta” stage.
- The software engineers still don’t know to programm an application that is location independant.
- The software engineers aren’t able to write meaningfull error messages
What do you think that such a message can be meaning. Of course that the location of your currently installed application is not ok.
In any case I would recommend you to use VMWare that works a lot better (according to my test) or VirtualBox.
Virtual box is becoming definitively an interesting alternative. It’s free, it works without hitch with Windows 7 and Open Solaris. The only point is that you cannot move the application away from the /Application directory (yes it’s one reason because I dismissed Parallels, but VirtualBox is free and comes from Unix System).
