Modern Ballistics

Long story made short: There is a new version of Modern Ballistics available here.

Long story made long:  As many of you know I wrote the exterior ballistics program Modern Ballistics.  I had the free demo require a license to be updated once a month by contacting server which kept track of how many computers were using the demo.  The user interface to the server had a limit of 100 computers using any copy of the software at a time.  It turned out that more than 100 people were using the demo in a month and new users couldn’t test out the software.  This happened just as I moved everything to a new computer and was in the middle of converting my code to use a new compiler.  I had deleted the old compiler off the old computer and I had no way to fix the problem people were having.  Last night (early this morning actually) I got the new build of the program tested.  To get things out quicker I just made the demo not require connecting to the server at all.  Then I had to update the installation process and test it.  Then I had to update the website.  I finished up about 0200 this morning.  Download the latest version here.

Let me know if you run into any bugs. The testing was rather “thin”.  In particular I am concerned about it working on various operating systems.  I only tested it on Windows XP and XP-x64.  I have a Win98 and Win95 available at home but I’m not home now.  Send an email to if you notice something broken.  Thanks.

  1. Installs fine, but when I try to run it, I get this error:
    “This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.”
    Reinstalling did not fix the problem. I am running Win XP Home with SP2.

  2. Please download the new installation package and try again. I’m not sure what is going on in your case but I just made some changes that will fix some other peoples problems and perhaps yours too.

    Let me know what the result is.
