Its been at least 8 years since installing the software from memory I think copied the files from the disk to the hard drive then installing them. There where instructions on the file step by step, at first it was asking for registration number. After performing step by step instructions it started working.

Thank you
The disk I have is Made in China.
I get to the point where I copy and paste to the hard drive, but when I try to
start loading step 1, an error will come up in German, and will not continue.
Must have a virus.
Did you order yours from a China company?

Dealers charge 0.3-0.5 hours to check and clear codes. My shop does it for local indies and body shops all the time......

Thanks, but I am sure once I get the program working, I will be able to do most maintenance on this car.
