Did you follow Wazzajnr's instructions?............
"To use the version of rave that I have here, the best option is to download the folder called "rave" and then simply double click on the "rave-lr.pdf" file. This will take you to the homepage where you can select your vehicle.
I know that is different to the video saintv8 has posted but that's the version I have and it works with whatever version of Adobe reader you have installed.
Alternatively, you can download the ".ISO" files but each of the three files covers a different range of models so you will need the correct one. I have now separated them into individual folders with models covered but I haven't tested them as I can't install a different version of Adobe on this laptop at the moment but they should work as per Saint's video."
Also see posts #17 & #18 in his thread re Dropbox.
Which did you download, and what happens when you try to run it?
