Would a LabVIEW 8.5 Executable play nice with LabVIEW 7.1 Development on the Same System?

[jmpugh]

Our testing computer right now just has the user run the corresponding .vi file since we have LabVIEW 7.1 installed on the computer.

If I use 8.5 to compile this .vi to an executable, I realize that I must install the run-time support for 8.5.  My question is what effect will installing the 8.5 run-time have on the ability to continue to run the other 7.1 VIs with LabVIEW 7.1. 

Should I be concerned with losing MAX settings when installing the run-time support for 8.5? I want to be able to run 8.5 executables but also able to open up a 7.1 .vi file in LabVIEW 7.1 and run it that way also.

Thanks for your help! I have 8.5 on my system and the idea is to slowly replace the running of the .vi files with .exe files, I was just curious in case my .exe doesn't work I can still run the tests with .vi in the mean time.

Thanks for your help folks!

Hi

if you ony install the Runtime Engine 8.5 it has no effects on your 7.1 development system.

Thanks Mike! I thought that would be the case, but wanted to make certain just in the off chance I was wrong and the entire testing process screeches to a hault while I try to "revert" back to 7.1.

Just note one thing - installing the 8.5 RTE should have no effect on 7.1, but if your executable requires drivers (e.g. DAQmx) and you install a version which no longer supports 7.1, you will lose the ability to work with that driver in 7.1. I don't think NI has any drivers yet which are not supported in 7.1, but I believe there are some which are no longer supported in 7.0.

Thanks for the heads-up tst! All of the .vi files I have run across on the system (I inherited the code) use the older DAQ. Would that possibly be included in the "etc." when discussing driver support?

I'm going to give it a try later this week. If worse comes to worse, I have the 7.1 install discs so I can revert back to it if I hose everything up (I think it will work, but I don't want Murphy to think I am getting cocky.)

I don't think NI even supports the old DAQ VIs anymore, as they were replaced with DAQmx several years ago. 7.1 should definitely support any version of those which 8.5 supports.
