Prebuild step of the veristand Custom Device template fails

[ARLROB]

I am using the Veristand Custom Device Template to start a new custom device, when I try to build my :configuration I get a build error, I know the error is related to the pre-build step.  Any ideas?

I guess you are following the steps in Implementing a Custom Device — VeriStand Custom Device Handbook 

The error comes from Utility\LLB Pre-Build CHM Build.vi

This pre-build VI assumes a CHM file name with "Custom Device" appended to it but the actual CHM generated does not have it. What I usually do is write the file name in that VI.
