IHMC CmapTools & CmapServer Support Forum

I have been using CMaptools on my Windows computers for decades, and now it won't load on any of my windows 10 or 11 computers. It installs, using the default settings, but when seeking to start it, it shows the initial load screen, and then just disappears, with nothing showing in the Windows Tasks.

Hold the Ctrl key down as you start the CmapTools and continue holding it until the debugging screen appears. Send me the error that is displayed.

Errors at end of start.
