Running a VI developed on a different version of LabVIEW

Is there any way to run a VI that was developed on LabVIEW 2018 on LabVIEW developmental version 2015?

is there any restrictions between 32 bit versus 64 bit?

You just need to downconvert the LV2018 VI to LV2015 (using the Edit->Save for previous… menu option).

As long as you don't call any DLLs (or similar external code relying on 32/64-bitness) it's no problem to load the VI in either the 32bit or 64bit version of LabVIEW.

No.  You have to "Save for Previous Version".  This still doesn't guarantee that it will run, because you will have to make sure that any tool kit that it depends on is installed in the version of LV that you saved to.  It's a pain to save all but the simplest VIs for previous version.

Yes.  Anything that is of one "bitness" will have to be represented in the other - e.g., both 32-bit and 64-bit versions of the same dll installed - or it won't work.  This includes drivers, so make sure the drivers are installed for both "bitness" flavors.  Pure LV stuff is source code and will compile regardless of bitness.

 

hope that helps.
