Unable to add regsvr32.exe to DEP exceptions

Hi, running thru an issue with an MS escalation engineer, I was asked to add regsvr32.exe to my DEP exception list. (A fairly normal if questionable 'fix' for 'Registry Server has stopped working' e.g. when installing certain apps). Ok... ah, but..

Clicking Ok, Apply, the window closed. No error msg. Just the usual warning about the risks of disabling DEP...

When I checked the exception list, regsvr32.exe had not been added. :eek:

But I can add other application exe's, including one or two from C:\Windows\system32\ (most are protected from being added).

What could I look for?

And just out of curiosity, where is the list of exceptions held? Not in plain text in the registry...

Thanks! dal987

Hi, actually it seems that regsvr32.exe is simply not shown in the DEP exceptions list although DEP is disabled for it. Any ideas how to make it visible?

- latest discovery - it seems I have disabled DEP for regsvr32.exe; the problem is it isn't shown in the list of DEP exceptions, which suggests I can't reenable DEP for it.

I can enable/disable DEP for it if I globally enable/disable DEP using bcedit.

(As seen in the DEP exceptions column in task man)
