2025Q3's new feature of saving project at older version source code and RTE

[Paul.B]

Hello,

I was trying the new LV25Q3 with the possibility to save a project with a source code of older LV version (later than 2017). That's seems pretty useful to be able to save to a lot of source code version with only one LV environment. However, when I try to create an application for this said project of older source code, the run time engine needed will be LV25Q3 (or Q1 https://www.ni.com/en/support/documentation/compatibility/17/labview-and-labview-run-time-engine-com...).

Will there be a possibility to build the exe that will need the RTE of same source code version ? So that if I code in IDE LV25Q3 with a source code of LV17, my RTE needed will be LV17 and not LV25Q3.

Paul.

Can I Build an Application for a Previous Version of LabVIEW Run-Time?

No. When an executable is built, the Run-Time Engine dependency is defined by the development environment used to create the executable.

Therefore, make sure that you match the version of LabVIEW Run-Time Engine to a compatible version of the Development System.
