Hi, I just installed Vectorworks 2008 the student edition. I initially downloaded it for windows and the program wouldn't run after I entered the authorization code. I uninstalled that and installed it with the dvd, but it said it wasn't compatible with the version of quicktime I was running and never prompted me for an authorization code. I uninstalled quicktime and vectorworks and reinstalled all of it from the DVD. Now, not only will vectorworks still not run, but iTunes isn't working either. I have also not been prompted for an authorization code. I have a PC and I am currently running windows vista. Any suggestions?
