When I do a certain action in my program, DEP terminates my process (the action does involve a COM interop if that makes any diffy?)

I know what DEP is, and how to turn it off, but it will not turn off for my exe... it syas that it must run with DEP on.

Any suggestions?

Yes, this is not a helpful answer however after repeated attempts to fix things the only practical solution was wipe the system and reload the OS.  Every time I have gotten a DEP error it boiled down to a improperly installed application.

Vista and your ANTI-VIRUS solution of choice will insist that it must have DEP.

I've temporarily switched it off entirely

bcdedit /set nx AlwaysOff

Bad move from a security point of view.

Are you sure you're getting the parameter types correct for the COM interop, and marshalling everything that's returned?

Pretty sure, the code in question has been untouched for months, and has never had a problem.

Hmm weirdness. A date issue perhaps somewhere in the COM component? I know DEP has triggered for me when i forgot to marshall strings and they ended up being disposed.

If you've recently installed .NET Framework 2.0 SP1 or switched to .NET Framework 3.5, then it's likely the problem has always been lurking, but previously went unnoticed.
