Dear Mr. Gold Squadron Leader, I complain about Microsoft enough in my day job. I am a technical product mgr. for a software company and I understand the Microsoft continuously screws the public by modifying the lower layer of an OS when it's not needed. But I also realize that we are responsible for making our clients happy by upgrading our software to handle new OS's. It usually takes quite an effort but not unreasonable. An effort that Lucas Arts should be quite capable of.
BTW: running just the .exe was already tried and still didn't work.
BTW again: I popped in Doom after originally writing this and it ran great. I will blame that on id software.
