USB Driver Installation Instructions for Windows Vista
(For all Ross-Tech USB interfaces with a current version of VCDS)

Note: These instructions are for Windows Vista only. Click here for instructions for older versions of Windows.

Instructions:

Download the current version of VCDS. If you have not yet downloaded VCDS, then click here to open our download page in a new window.
Allow VCDS to install itself, but please do not install it in the Program Files tree!
On Windows Vista, we strongly recommend installing VCDS in C:Ross-TechVCDS or a similar location.
Plug your Ross-Tech USB Interface to your PC's USB port
- It is not necessary to connect the interface to a car yet.
The New Hardware Found Wizard should appear:
On the screen above, click 'Locate and install driver software (recommended)'
The following dialog should appear:
On the screen above click 'Don't search online'
The following dialog should appear. The name of the interface may vary.
In the dialog above, click: 'I don't have the disc. Show me other options.'
The following dialog should appear:
In the dialog above, click: 'Browse my computer for driver software (advanced).'
The following dialog should appear:
In the dialog above, you can type the location where you've got the appropriate drivers and then click the [Next] button,
or you can can click the [Browse] button and browse to it like this:
On the Browse screen above, you must click the [OK] button once you've selected the correct folder.
Once Windows Vista finds an appropriate driver, it will begin installing it and present you with the following dialog:
Here it would seem that Microsoft has a terminology problem. This dialog appears even when we sign our drivers with a Class-3 Software Publishing Certificate from Verisign and the appropriate cross-certificate from Microsoft, which should according to all available documentation allow Windows to verify the publisher (Ross-Tech, LLC).
We believe that the message actually means is that the drivers haven't been WHQL certified by Microsoft something which is the case because it's an expensive hassle.
In any case, you must click on 'Install this driver software anyway'.
Windows will then finish installing the driver and you should see a dialog like this:
In the dialog above, simply click the [Close] button.
Start VAG-COM.
Click the [Options] button.
Select the USB Port.
Click the [Test] button.
The results should look something like this:
Go test on a car..;-)

VCDS-Lite for all 3rd party and 'Dumb' Interfaces on 2005 or older VAG cars

VCDS-Lite is Copyright 2012 by Ross-Tech LLC / Uwe M. Ross. All rights are reserved.
De-compilation, disassembly, reverse-engineering, alteration, use as a reference tool for the purpose of developing a product with similar functionality, and re-distribution in any form without the prior written consent of the author is prohibited.
The unregistered shareware version of VCDS-Lite is free for non-commercial use, but no support of any kind is available. Use in a commercial environment requires registration.

By downloading this software, you acknowledge that this Program is provided 'as is' and 'with all faults, defects and errors' and that all use of the Program is at your own full risk. It has been extensively tested, but we cannot guarantee it will work correctly with every system in every car. We will make our best effort to fix any bugs and to enhance the program, but we specifically disclaim any liability for damage to your computer or your car, and we do not promise to have any particular enhancements available on any specific date.

Instructions:

If you have a HEX, KEY, KII, or Micro-CAN interface, you're on the wrong page. Please go here instead.
Download the self-installing distribution file.
Run it and follow the prompts to allow it to install itself.
You must install VCDS-Lite on your PC's hard disk! It will not work properly if you try running it directly from a 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 supply interfaces for VCDS-Lite. VCDS-Lite works with some of our old interfaces from many years ago, as well as many 3rd-party interfaces.
Turn the car's ignition switch ON. No need to start the engine.
Start the VCDS-Lite program:

Click [Options] and select the correct communicationsport.
Use [Test] to confirm that the program can use the port and find the interface.
Then [Save].

Now Play. Make sure the software can reliably access all the control modules that it should in your car. See our Application Charts. Read Fault Codes from some modules.
In order to get access to some of the more advanced functions, will need to register and activate the software. The exact differences in functionality between the unregistered/shareware and registered/activated versions are summarized in this handy chart.

Note to registered users updating from older versions:

If you're updating from VCDS-Lite version 1.0 or 1.1 you should not need a new activation.
Simply install VCDS-Lite in the same location and it should use your existing activation.

If you're upgrading from an older version such as VAG-COM version 311 or 409, you will need a new activation.
- First, install the VCDS-Lite and test it thoroughly in shareware mode as described above.
- Then go here and fill out the appropriate form - or buy a license if you don't have one yet.

Release Notes:

VCDS-Lite works with most 3rd-party 'Dumb K-Line' interfaces
as well as the following ancient low-tech Ross-Tech Interfaces, the last of which we sold early in 2004:
ISO-COM, FAST-COM, MAX-COM, BI-COM, TWIN-COM, and UNI-COM.
VCDS-Lite works with all standard versions of Windows, from Windows 95 though Window 10.
Both 32-bit and 64-bit Windows builds work fine, but if you're using a 3rd-Party USB interface, keep in mind that it is your interface supplier's responsibility to provide a driver for his hardware.
VCDS-Lite does NOT work on Windows RT
Windows RT runs on devices with ARM (instead of x86) CPUs and normal Windows programs like VCDS-Lite simply do not work on them.
The default installation folder is C:Ross-TechVCDS-Lite
If allowed to install in the default location, it should not interfere with an existing Ross-Tech software on your PC.
To remove older versions, simply delete the shortcuts from your Start menu and Desktop and delete the old folders which are normally:
C:VAG-COM or C:VAG-COM-Beta or C:Program FilesVAG-COM or C:Program FilesVAG-COM-Beta
