Running VDASH in virtual environment is not allowed because of very unstable USB connection with DiCE.
We tested to run VDASH and car programming in virtual environment for a long time and at the end, we decided to forbid using VDASH in virtual environment because of lot of troubles with USB connection speed and stability, what is the main part of successful car modules programming.
Please install VDASH into native operating Windows 7 / 8 / 10 system.
You can do that even on MAC with bootcamp - https://support.apple.com/en-us/HT201468
Thank you for your understanding!
