How do I get a clean uninstall of NIDAQmx 8.8

[gordon akst]

We have been using NIDAQ 6.9.3 with several different DAQ devices with Windows XP.

We found that the new device we wanted required NIDAQmx, so we were told to download and install it.

We discovered that our existing C++ software will not run with NIDAQmx, so we uninstalled it and reinstalled NIDAQ 6.9.3.

We now cannot run any of our applications using NIDAQ or even the NI MAX program, which gives an error indicating corrupt installation.

How do we get a full uninstall of NIDAQmx so we can get a clean reinstall of NIDAQ 6.9.3??

Help!

Hi Gordon,

Thanks for the post.

I would recommend using MsiBlast.

Please find the steps in this forum link. 

Hope this helps,

Hi Gordon,

It sounds like there is a MAX database corruption, which should not be too difficult to fix. Take a look at the following KnowledgeBase article and follow the steps listed.

Once you have completed the MAX corruption recovery, you can make sure the NI-DAQmx is un-installed and then re-install a copy of Traditional NI-DAQ (Legacy) 6.9.3, which can be found at the following link.

If the above steps don't work then, you could try to use MSI Blast, as mentioned in the previous post, but I would save that as a last resort. Also, if this is the option you need to go with you will have to contact NI for support and open up an email or phone service request.

Your C++ program will not run the DAQmx driver, because DAQmx and Traditional NI-DAQ use different function calls that do not have a 1 to 1 mapping relationship. It will take a small amount of effort, to modify your existing code to use the DAQmx driver. For a list of C functions and their definitions you can check out the DAQmx C Reference Help, which will install with a copy of the DAQmx driver. You can find that under the NI-DAQ>>Documentation path in the Program Files of your Start menu.
