NI-DAQ 6.9.1. with 2 versions of CVI

[Manfred Rieder]

Thanks Jason ! I meant, of cause, the latest version of NI-DAQ 690 and 691. It does not allow anymore to install into 2 separate folders, where the 2 CVI programs are seated. CVI6 and CVI5. Please help. How can I run my 2 Versions of CVI with NI-DAQ 590/1.
When this NI-DAQ is installed once one can select the target folder. When installing again for another CVI in another folder, the 'target'-Browse Button Option has disappeared. I really need to run 2 Versions because some Companies are still using older Versions of CVI ! Some DAQ Carsd and Win2000/ME need latest NI-DAQ. I have to stick to CVI 5 for the moment.

The NI-DAQ installer no longer detects, multiple versions of CVI. It just detects the current version. You will need to copy the NI-DAQ files from the new version of CVI's directory to the old version. The files you need to copy are the following:

From cvi\bin:
easyio.lib, easyio.lfp, dataacq.lib, dataacq.lfp, dataacq.pth

From cvi\include:
easyio.h, dataacq.h

From cvi\extlib:
easyio.lib, dataacq.lib

From cvi\samples:
The entire \daq directory.

Copy these files to the same locations under the previous version file tree and data acquisition should work.
