Hi Manxie
you can turn off Data Execution Prevention for everything!! by following these steps...
Click on the Start menu and in the search box, type "CMD". Right-click on the CMD shortcut that appears and select Run as administrator.
Then type the following:
bcdedit.exe /set {current} nx AlwaysOff
It should say that everything is ok.
To turn it back on again, type the following
bcdedit.exe /set {current} nx AlwaysOn
Good Luck
and tell us how you get on.
Mike
