PCGU1000 doesn't like sw rev 4.0: No Function Generator resp

With PCLab 2000 SE version 3.03 and driver version 4.40.1.0, the PCGU1000 is recognized properly.

I then downloaded the shiny new PCLab 2000 SE version 4.00, with driver 5.4.0.0. The On/Ready light never comes on, and the function generator software pops up the “No Function Generator response” message. Rebooting the computer, detaching and reattaching the USB cable, detaching and reattaching the power cable – nothing works.

Driver version 5.4.0.0 isn’t recognized by software version 3.03, so I can’t pin blame on the driver.
Driver version 4.40.1.0 is recognized by software version 4.00, but the software is still unable to communicate with the function generator.

Windows XP SP2, VMWare Fusion 3.0.1, OS X

Solution / Bypass:
When you start PCLab 2000,
right-click the icon, and choose: “Run as administrator”

The PROBLEM, and my way to get it running:
I had just bought the PCGU1000
and when I tried to get it to work I experienced the same problem as a lot of other people have done.
“No Function Generator response”

On my computer I have Windows Vista.
I did NOT install the software for the enclosed CD,
but I downloaded the latest (current) versions of driver and software from Velleman.
Installed versions:
PCGU1000 driver: v5.4.0.0
PcLab2000SE: v4.0

When I conneced the power-adapter to the PCGU1000, I expected the ON/READY-LED to lid, but nothing happened.

I connected PCGU1000 to my PC via the USB-cable.
Installed the driver,
and started the PcLab2000,
and when I tried to send commands from PcLab2000 to the PCGU1000 …

… I got this INFORMATION-box:

" [i]No Function Generator response.
Check the power adapter connection.
Disconnect and reconnect the power adapter and restart PcLab2000SE.

If the User Account Control (UAC) is on, then PcLab2000SE has to be run under administrator account.
Right-click on the PcLam2000SE icon on the desktop or in the the program list,
choose Properties, switch to the Compability tab,
select “Run this program as an administrator”. [/i] "

I tried to repower the PCGU1000 and restart PcLab2000 several times, without success.

I checked the Output-voltage of the power-adapter: 9.5Volt ,
so the power adapter was OK.

Because I did not se any light from the “ON/READY”-LED, my next thought was that the PCGU1000 could be defective.
But it was absolutely new and probably testet before leaving the factory.

I did then take my time to read the second part of the Information-box,
and got the clue.

It’s a great tool.

This problem occurred after the Windows Vista was released.
There is the UAC (User Account Control ) preventing the software to communicate with the external devices.
This is the reason why this text was added to the Information-box in the latest release of the PCLab2000SE:

[color=#0000BF]If the User Account Control (UAC) is on, then PcLab2000SE has to be run under administrator account.
Right-click on the PcLab2000SE icon on the desktop or in the programs list,
choose Properties, switch to the Compatibility tab,
select “Run this program as an administrator”. [/color]
