Let me get this straight you want apple to support a beta version of an os??? Give me a freaking break. Good god.
Hmm, it's a wonder this installed perfectly fine under 10A261 wow... imagine that, Apple supporting a beta version of an OS, wow.
Considering this is the only piece of software to give me trouble, I'd say Apple did something pretty non-standard to cause this, which wouldn't be good practice and shouldn't be done, but what do I really know.
Also, the 'beta os support? lawl' argument is the same one that people used when Vista was new and then it got a bad wrap for it's poor hardware support out of the gate, and of course now that all those drivers are out and working and Windows 7 uses the same driver backend... people love Windows 7? Coincidence? Hmm.
And why would you need a break for something I'm complaining about Apple doing? You take offense to Apple's poor support of something they're trying to sell to Windows users as well? That's amazing, selective offense, if Apple does it wrong, everyone tells the person who's complaining that they're wrong, but if Microsoft does it wrong they complain that Microsoft is in the wrong...
Not to mention that the previous MobileMe CP installer worked just fine... and still does... in Windows 7.
The point of Beta testing is to get your software working before the release happens, so that the transition is seamless to end users, something that Apple, who has paying windows customers for the MobileMe service, would want to ensure...
Notice my post is dripping with sarcasm, where as yours was borderline attack... but ok.
