Custom Device Builds not working - 'unable to load' error.

I am having difficulties building a custom device in LabVIEW and then getting it to work in Veristand. 


I used the custom device template and it builds ok without errors but when I try and load the device in Veristand I get an 'unable to load file' error.


I have the 64 bit version of LabVIEW 2018 and Veristand 2018; is this the reason? As far as I am aware there is no 64 bit version of Veristand, so how do I compile the custom device in a suitable format for Verstand to load without chucking up errors?

In general, 64bit application doesn't call 32bit app/dll, vice versa. 

Because there is large difficulty to call and use.

Why did you develop on LabVIEW 64bit?

The models can be built only in 32 bit version of the LabVIEW as VIs contains compiled assembly, that is loaded by VeriStand.exe
