Vista and DEP

[torrid]

On Vista, the installer installs fine but when a user with DEP "on" runs our application it throws and error and kills it.

Of course the USER blames US. Is there a way to disable DEP during install?

Or, do we have to add a screen to install telling them to disable it for our app?

If that's the case is there a way to detect if DEP is enabled or not?

ANy help and advice in this area is much appreciated...
