VCDS will run on PC, including W10, Windows tablets, and on Mac running Windows VM. The software is a free download, so you can have as many copies installed in as many places as you wish. Licensing is done through the physical cable.I'm interested but a little green when understanding the details. I own an '04 V8. Will yours work with mine? Do I need software? Is the license unlimited? This only works with PCs…right?
