Where can I download the VCDS program?

I bought a VCDS non genuine cable off Ebay and the seller sent me a message containing a link to download the program, which I did and it all worked perfectly.

I've since had a new laptop so I want to do the same installation process again but the link in the Ebay message no longer works and the seller's account does not exist anymore so I can't contact the person again.

Does anyone know where I can get a download link from which contains the Ross Tech program that will work with my knock-off cable?

Yes, yes, I know I should stop being a tight arse and purchase the genuine product but for the tiny amount of use I get out of it I just can't justify the steep price of it.
