Fix Disappearing InstallShield Installers by Disabling Windows DEP

The other night I was trying to install Panasonic’s GTWIN on my Windows 7 machine and the installer window would disappear when I got to the installation progress window.  The InstallShield icon would still be present in my taskbar and the processes would still show up in the Processes tab in Windows Task Manager, but the window itself was just gone.

After a bit of googling, I came across a forum post that suggested disabling DEP.  After following this guide on VistaForums, I was able to successfully install GTWIN.
