trying to use LAB-PC with lab windows 7.00

[ed austin]

First I installed ni-daq 7.1 that came with the distribution. This did not recogonise LAB-PC+ board, so I attempted to install Ni-DAQ 6.9.3. The installer says it is attempting to add 6.9.3 driver, and lab windows support, then when I press 'next' it immediately says the driver installation is complete, without doing anything. How can I fix this?

Hi Ed,
The last driver which supported LAB-PC+ was 6.9.3. The way the driver software works is that the latest driver version installed is held on the PC and it is impossible to install earlier versions because of this, you see the behaviour which you describe as the later driver version prevents 6.9.3 installing. The only way to install 6.9.3 would be for you to uninstall NI-DAQ 7.1 and then install 6.9.3.
I hope this helps,
