I have a database client (4D 2004 Client... which, for the record, I vehemently hate but am forced to use because our company is still running this) that I'm trying to run in Windows Vista SP2.

I've added the program to the DEP Exceptions list (per a 4D tech article detailing this problem... sorry, can't find the link now) and restarted the computer, but every time I try to log-in to our remote database, the program is shut down by Vista, citing a DEP event. And yes, I have restarted the computer several times, so the new DEP settings should be in effect.

I'm a bit confused at this since I specifically added the 4DClient.exe to the DEP Exception list!

I realize that very few (if any) of you might have this exact problem with this exact program, but can anyone shed light on the fact that DEP still seems to be enabled for a program that I've specifically added to the DEP exception list?!?

Any chance the 4DClient.exe is spawning other processes that themselves need to be on the exception list? – mindless.panda Mar 5 '10 at 16:16
Not sure; how might I find that out? The program file folder only contains one executable... – neezer Mar 5 '10 at 16:47
Have you tried disabling DEP completely temporarily to see if it resolves the issue? windows.microsoft.com/en-US/windows-vista/… – heavyd Mar 5 '10 at 16:58
@heavyd I would if I knew how; I've already done everything listed in the link you sent me, and that doesn't work. – neezer Mar 5 '10 at 17:01
I would think that limiting it to essential Windows programs and services would be okay, but this article explains how to disable it completely, although I wouldn't leave it disabled permanently. support.microsoft.com/kb/912923 – heavyd Mar 5 '10 at 18:04
