For working with the computer VinciLab makes use of the Microsoft RNDIS drivers. Some older versions of the RNDIS drivers may give problems. How do I solve that?

There is a hotfix available for Windows 7, Vista Windows Server 2008 R2, Windows Vista or Windows Server 2008, and a separate hotfix for Windows XP.
After installation of the hotfix use the Device Manager to uninstall the VinciLab driver while VinciLab remains connected to the computer via the USB cable. Then disconnect the USB cable from the computer and connect it again to use the new Microsoft RNDIS driver.
