Yes- that did fix the issue. I moved "Create control.vi" out of the C:\Program Files (x86)\National Instruments\LabVIEW 2018\project\UI Tools\Control Generator directory, opened LabVIEW 2018 SP1 (which now launches without crash), moved "Create Control.vi" back into the original directory and mass compiled the directory and now everything works. I appreciate your assistance and I apologize for digging up an issue with an outdated version of LabVIEW but some of us are stuck on older versions.
Again- Thanks!
