floppy or CD. However, you can use a floppy or CD to move the distribution file from a PC
with internet access to another PC that does not have internet access.
Connect an appropriate interface between the computer and the car. Ross-Tech does not

VCDS-Lite works with all standard
versions of Windows, from Windows 95
though Window 8.
Both 32-bit and 64-bit Windows builds
work fine, but if you're using a
3rd-Party USB interface, keep in mind

VCDS-Lite should work fine once

Windows programs like VCDS-Lite simply do not work on them.
