This is not my software. Visual Math Editor is a tool written by David Grima and can be downloaded from his own website here:
http://visualmatheditor.equatheque.net/index.html
The reason I am redistributing this code is that the version available to download via David's site is rather out of date (2.0.33) but the version he himself is hosting is much later, 2.0.58, and it has some fixes which were important to the users I was supporting at the time.
David did not respond to requests to make a later version directly downloadable.
As can be seen here, the software is licenced for distribution under the GPL3 licence so I believe am I compliantly making this latest version available.
