I maintain several machines in our factory, all running various versions of LabVIEW executables. One of the many versions I have installed on my machine is LabVIEW 2018 v18.0.1f4 (32-bit).
It's been 'many moons' ago, but I remember updating my 2018 runtime to SP1 f5, but I haven't had to build an installer in 2018 since then.
I ran into a situation yesterday where I needed to create an installer in 2018 and left "Automatically select recommended installers" checked, which auto-selects the 2018 SP1 f5 RTE.
When I select "OK" in "Additional Installers", the "Select Source" dialog appears with a single entry, which is a 2018 application that I had built and installed on my local machine. Clicking on "OK" prompts for a media path as expected, but I don't have (or can find) and installer for 2018 SP1 f5. Even pointing it to the installer it's referencing (that I created) gives me an error message stating that the "...media you have provided is a different version of the requested media" (which it isn't).
I ended up giving up on creating an installer in 2018 and recompiled everything in a later version of LabVIEW since I needed to get an update deployed immediately. However, I am curious whether anyone has any insight into this. I can't be the only one to have seen it.
