In my opinion, Bernd Nowak of the GPLPS has just released a program that, at least in this stage of GPL's lifespan, may be one of the greatest programs created for GPL.
Even the experienced GPLer among us has at one point or another struggled with a new GPL installation. And this is not to mention the problems that newbies to GPL experience. And you'll occasionally read comments from long-time GPLers that are having problems with GPL on newer pc's/platforms. The answer to all of these questions is the GPLPS GPL installer. It will give you a working GPL installation, with updated GPLEA cars and some of the finest track updates around for the original GPL venues. You can read more about it here:

If you've been struggling with a GPL installation, your answer is at hand...
