I get the following error when I run prepomax v2.2.0. I do not understand this error as GmshCommon.dll is available in the lib folder.

This occurs when I try to create a Transfinite Mesh

Move the PrePoMax in a non-system folder.

This is the same issue reported under General Questions - Extrude meshing question  
Solved by copying the missing DLL’s from Trevor’s Dropbox on Feb 7 to the lib directory
