After installing LV 7, MAX 3, NIDAQ 7, can not target to LV 6.1 RT even after uninstalling and loading older version.

We have started using LV 7 for all of our new projects but still have to support a number of older projects made in LV 6.1. After installing LV 7, MAX 3 and NIDAQ 7, we can not do remote DAQ configuration on the older version of RT and can not target to the RT system either. We used NIs uninstall for MAX and NIDAQ and then reinstalled the older versions, but we still can not remote DAQ configuration. Computers that have the older versions of MAX and NIDAQ and have never had the newer versions installed have no problem with remote DAQ configuration or targeting.

How can we go back to the previous version of MAX and NIDAQ and get it to work? What is left
after uninstalling the newer versions?

Unfortunately, LabVIEW 7.0 will not target LabVIEW 6.1 RT. I would suggest using separate systems for LabVIEW 6.1 and LabVIEW 7.0, when you need to target remote devices such as RT. To take the new system back to version 6.1, uninstall LabVIEW 7.0, NI-DAQ 7.0 and MAX.

We have already done that. And that's part of the problem. After a "full" uninstall and then installing LabVIEW 6.1, Max 2.2 and Ni-DAQ 6.9.3, we still can not target to the test stand or connect with MAX (remote DAQ configuration). This computer had no problems connecting before loading LV 7, etc.

Rob,
I would recommend creating a Service Request on-line and contacting an Application Engineer. There are several possible reasons that software might not be completely removed, and we have some utilities that will make sure this does not happen. There also might be some issues with downloading the code to the "target". We could quickly reformat the controller and make sure to get the older software on the system.
