VISA and NI-488.2 Runtimes question

[billko]

Hi, Everyone:

I have LV 2012 installed on a PC.  I want to run a LV 2016 executable on it.  For user convenience, I would like to install it with the LV installer.  The installer wants to install the VISA and NI-488.2 Runtimes (which I cannot deselect from the installer) in addition to the LV 2016 Runtime.

Now the question:

Will the LV 2012 installation want to use the new runtimes, too?

Thanks!

I think LV 2012 development environment will continue to use the installed drivers, however I think the NI-VISA runtime will be upgraded to whatever you bundle with your installer (say 16.0). Unfortunately LV 2012 is compatible with NI-VISA <= 15.5, so now you cannot run LV 2012 executables that depend on NI-VISA.

I believe this is how it would work, I hope someone can confirm or deny. Options would be (in my order of preference):

1. Back-save your application to 2012, and build an executable using LV 2012
2. Install a virtual machine on your LV 2012 computer, and install your application on this virtual machine
3. Install your application on LV 2012 computer and face the compatibility issues I mentioned
