Eek.
I spent 5 hours or so working through multiple problems getting Windows up on my Mac so that I could play Osmos. I ended up going to sleep, finishing in the morning, just now.

But alas! "The application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem." Are there any known bugs with Boot Camp on macintoshes?
(needless to say I've restarted the application, as well as reinstalled it. I've not been able to find any error logfiles, but if you can point me to the location I can tell you what's in it.)
Edit: And if I run it from Console, it says The system cannot execute the specified program. Perhaps I should try redownloading.. *tries* Nope, same error.
Edit: Aha, I may need visual c++ 2005 runtime libraries. [update: that seems to have done the trick. no error, at least.. about to see how it works! (it does!))
