You can download the latest software package and the driver from:
velleman.eu/support/download … 1000&type=
You can use the driver: "PCGU1000 USB driver for Windows XP (32- and 64-bit) / Vista (32-bit) / Windows7 (32-bit)"
This driver can be used after the “workaround” for 64-bit Windows too.
In the software package there are three files:
- Run this software to install the PcLab2000SE v4.05
- Includes instructions how to update the USB driver.
- Please see this section: “Workaround to use the PCGU1000 on 64-bit Windows”
- Follow the instructions in the Release Notes.pdf and run this program to get the PCGU1000 working on 64-bit Windows.
