Guys, you're all (including Digitec!) making it a bit easy for yourselves.
Windows version: Take a look at the reviews.
The PC software supplied on the mini-CD is called 'DMM'. There are all sorts of other things on the CD itself, but I'm not going to type that out now, the Digitec clerk can do that if he wants to sell something - or he could post another photo. I have one, but unfortunately I can't upload it here.
Since you obviously can't communicate with Digitec itself, I'll try this: I'm increasingly dissatisfied with the product descriptions in the online shop. If you would do them properly, there would definitely be far fewer returns. Maybe I'm a bit old-fashioned, but I think a seller should know about what they're selling.

You can download and use the drivers and software as a zip file from the manufacturer. Best regards

Hello. Unfortunately I did not receive any help or answer from Digitec! After a long search for the working software "VA40R DMM", I am now running Windows 10. Reviews and comments are helpful. Urs E.
