Has anyone ever not been able to get a particular Windows app to open on their Mac? I have searched to no avail (maybe I just fail at searching). Until now, I've never had a problem getting ANY Windows application to open on my Mac using VMWare Fusion, let alone when booting "natively" into Windows XP using boot camp. I've installed (without a problem) a MoTeC ECU management program (called ECU Manager) but cannot get it to start. I've done all the standard Windows troubleshooting things like reinstalling, disabling virus and firewall software, checking permissions, removing all references in the registry before re-trying etc etc. No go. I can get the software to work on a borrowed HP laptop and also my PC desktop without a problem. What to do? I really need to use this software on my laptop. I only bought a MBP because Windows and all Windows software run on them. Seems I was wrong? I would be really disappointed if I have to go out and by a PC laptop. May as well sell the Mac if I can't use Windows software. Can anyone suggest how I could get this software to work? MoTeC are no help because I've put it on a Mac (even though it's on a Windows partition).
