Access violation running PClab2000SE 4.03

I have built the K8047 kit - 4 channel USB data logger, and have successfully used version 3.03 of PClab2000SE suplied on the CD. However, when I try to use version 4.03 downloaded from the Velleman site, I get the following error:[quote]Access violation at address 0024488C in module ‘CP210x.dll’. Write of address 7C59C354.[/quote]This message then repeats in cascading windows every second until I kill the program with task manager. I don’t know if they are any different but I have tried the CP210x_VCP_Win2K_XP_S2K3.exe bundled with the download as well as install_drv from the 3.03 start menu and also the 4.03 start menu but all give the same result.

Is there a specific driver or an updated DLL and how can I tell which driver version is installed? The only devices I can find in device manager are HID-compliant device and USB Human Interface Device both of which show a Microsoft supplied driver.

I am running Windows 2000 SP4 with 1Gb of RAM.

Thanks,

Julian

The module ‘CP210x.dll’ is needed for the function generator PCGU1000 only.

Also the CP210x_VCP_Win2K_XP_S2K3.exe is needed only for the function generator PCGU1000 to run under 64 bit Windows.

The K8047 is a HID (USB Human Interface Device) device and needs no driver to install.

It seems that the installed PCLab2000SE v 4.03 is corrupted.

You may try to download and install it again.

If still problems then you can use the CD version 3.03. There are no modifications in the software for the K8047 / PCS10 since the v3.03.
