How can I build a LabView application that uses the 2012 runtime, on a development system with LabView 2013 or 2014 installed?

[MatCrawford]

I need to build a LabView application .exe to run with the 2012 Runtime, for legacy support. I currently have LabView 2013 installed on my development system, and have 2014 available. How can I build an application that uses the 2012 runtime on this development system? Do I have to downgrade to 2012? Thank you.

To build a 2012 application, you need 2012. Why can't you install the 2013 runtime and build with that?

We have existing customers that have installed our application that was originally built with 2012 (provided by a contractor that is no longer available).  Due to IT regulations, it is far easier to update these customers by simply replacing the .exe file, than creating an install that their IT department must run.

If I have to downgrade to LabView 2012, where can I get the installation for this?
