actually, i don't think there are any registry settings (what I meant by hooks above) confirm?

"You don't have to disable DEP per say, in fact," Understood, and adding the exception is what I had done. But in either case is an admin function to deliberately work around a security feature, and gets frowny points from those who would care about such things.

"am i like special or something?" you just might be. It really depends on the security policy set for the PC, and likely will only come up in a managed WinXP pro setup. I had no issues other than turning off DEP, and I'm running Symantec AV and Windows firewall is up, etc. DEP is only supposed to get set off something tries to run executable code from a memory page that is supposed to be data only. Now, not being an application developer, I have no idea about the how you would actually control such things. It may be that symantec does something when you run the continuum executable that sets off DEP. I'd buy that. But what's different between Continuum and my Nintendo emulator sitting on the same thumb drive. One sets off DEP, the other doesn't.

sorry, should have posted this right away. So the problem was the DEP. Shortly after posting this I came across the security software issue thread. Copy paste does work as long as DEP is not turned on on the machine. I have a laptop with DEP enabled, and I had to log in as admin and call out the Continuum executable as a DEP exclusion for it to run. Everything is fine after that. On a computer without DEP, there are no further restrictions. On computers with DEP, the exclusion needs to be updated any time the file location changes (if you move the folder on the flash drive, or if the flash drive mounts with a different drive letter.) To the best of my knowledge, there is no need to run the installer on the PC you want to play on. Obviously, running off thumb drive isn't possible on a computer with DEP if you don't have Admin. no school computer lab playing with super low latency for me So I've had other executables run off a thumb drive even though DEP was enabled, and haven't had to set exclusions. What is it that triggers DEP? is it that it's a network aware program? Edit: according to microsoft, it is recommended that DEP not be disabled. Instead, the author or vendor of the offending software be contacted and asked to fix their software to not violate DEP.
