This looks way to technical, even for me. It would be much better, if SecuROM would make a SecuROM removal tool like Starforce did. I installed Dreamfall which uses Starforce, I then un-installed Dreamfall some timer later. And downloaded the Starforce removal tool. Presto - no sign of Starforce of the computer. I'm not saying that SecuROM is a threat to the computer, butit could be used as a carrier of virus and trojans - sometime in the future.
Right now, I'm frustrated and mad

since nowhere, not in the preview or in the demo release readme, that the demo would install SecuROM software on our computer or that the demo (maybe?) only allowed us 2 (or 5) installs all together.
Or that (perhaps) there would be a time limit on the demo so that it would be null&void after a week or so...
Anyway, I keep getting the error 'you don't have access to the appropriate rights' for this program, even after a fresh download from Gamespot, yes, even, after a fresh install from Steam, the demo will not play

I'm not a happy camper right now, as you can tell. If I had known about this, I would have waited untill a PC Game Magazine had the Bioshock demo...
However, I might be tempted to use the advice from Tom's Hardware just to see if it is the SecuROM files on my system that makes it so that I can't play the demo.
(since I apparently installed it 2 times to many...) If I do, would system restore point then count as 'backup of the entire system' ??
