Automated DEP OptOut/Exception NOT Working

Microsoft Microsoft windows xp pro full...

Specs: XP Pro x86 in Svr'03 AD environment, Core2Quad Q9300 4G
I've got all our boot.ini files set with /noexecute=optout, and there's one app that doesn't work with DEP (ISIS Pro scanning software). So i added it as an exclusion via a regedit:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]
"C:\\DocuWare\\ISIS PRO.exe"="DisableNXShowUI"

and pushed the registry change via GPO. This ADDED the exe name to the exceptions list (Sys Properties, Performance Options, DEP tab) with a little check in the box and everything. Only problem is, the software does NOT behave as though it is excluded from DEP: I have even used Process Explorer (MS Sysinternals) to verify that despite being added to the exceptions list, ISIS Pro is running with DEP enabled.

You know how we fix it? Log into each machine as an admin, UNCHECK the box (apply), and RECHECK the box (apply again).

any clue as to why the registry setting that worked for so many others is giving me the bird? I'm baffled that the system seems to think this exception has been made, yet behavior does not reflect registry/system settings.

Thanks for the responses.

Stupid question, but were these PC's were rebooted after the registry change was made?

yeah, the change occurs as part of a startup/shutdown script.
