1. We use open source installation software called Nullsoft to build setup files. Here is the link to its web site: [url removed, login to view] to download a copy. Please develop a Nullsoft script to create and install file for the 'unregistered' gCADPlusversion. I am not sure how it is done, but if possible an install with the .msi extension rather than the .exe extension is preferable (not sure if Nullsoft can do that). The intention is to put the resulting unregistered version of gCADPlus on our web site as a trial version.
2. Make a version of gCADPlus that opens a Vec file and allows a Save to dwg (and the ability to print). One menu only - the File menu. This version should not have a command line, no drawing ability, no editing ability - just load Vec and save as dwg.
