Ok, looks like i got more than i bargained for!
Its an NRG file from memory, which means its a type of image file.
You can do one of two things, use nero to burn an image to cd and then you run the software from the cd.
Or you can mount the cd to a virtual drive, i use poweriso, google it, its free.
So, just extract the rar file you downloaded to some place on your pc, once done, go to the extracted file, left click (assuming you've installed poweriso) and choose: poweriso then mount...
Then, you'll see on the left of your file explorer a new cd drive, open it and install the software.
Once installed it will place an icon on ur desktop which is the application file. But each time you run it, you need to remount that nrg file again.
So if i were u, burn the image to cd, and just install the cd whenever u require the software
You can use most cd burning software packages to burn cd images to cd, Nero is one, poweriso will also do it and its freeware.
Sorry i using mu iPhone, my instructions are stilted i know!
Ill write clearer ones when I'm at my computer later today.
When you buy the manual from ebay, it comes on cd already so you don't need to jump through these hoops, but as this is a download, it's been converted to a cd image file, so this cant be avoided.
