Running VDASH in a virtual environment is not allowed due to a very unstable between the USB connection and DiCE.
We spent a lot of time running VDASH and car programming in a virtual environment and eventually decided to forbid using VDASH in said virtual environment as the USB connection speed and stability bring more problems than solutions.
Please install VDASH into you native operating Windows 7 / 8 / 10 system.
You can even install it on MacBooks using boot camp - https://support.apple.com/en-us/HT201468
Thank you for understanding!
