so essentially I just need to burn the image to disk or create a virtual disc on my machine so it runs like a programme
will have to spend an evening figuring it out with a bottle of vino for company
Once you have extracted the "ROM" from the .rar, you need to mount the disc (not as much fun as it sounds in fact). If you don't have any virtual drive software installed you'll need to download some, I use "Daemon Tools Lite" it's free forever, easy to use and does the job with minimal nagging to upgrade to a paid version - but there are many other similar programs to use. I once spent a weekend trying to get Microsoft's version of the service working, to no avail. I'd avoid that if I were you.
Following the instructions in your chosen virtual drive software find and mount the disc. It should then show up in "Computer"/"This PC" as an extra CD/DVD drive with the disc loaded. Right click and "Open" the disc in explorer to locate the "setup" file. Double click and follow the installer instructions, it will ask you (in Italian) if you want to create a desktop shortcut, if you don't then it will still create a programs menu shortcut. The "disc" will need to be in the "drive" for the program to run - if your virtual drive doesn't start with Windows and automatically mount the "disc" then you'll need to start it and mount the "disc" manually whenever you use eLearn.
Click/double-click the shortcut and eLearn will open, select your language and vehicle and your done.
There is absolutely tons of really useful info on it - but I find the layout and menus less than helpful. I mostly tend to use the search function to find stuff.
A bottle of nice chianti, should make the process completely painless.
