When you attempt to Launch Graphical Analysis version 4 on Windows, you may get an error message that says:

This is caused by a missing or corrupt Microsoft Visual C++ redistributable.
1) Go into Add/Remove Programs and check to see if you have “Microsoft Visual C++ 201? Redistributable (x86) 14.?????” (The year will be either 2015 or 2017 depending on 14.0 or 14.1.)
2) If you do have it, remove it, (make sure you don’t remove the x64 version by mistake.)
3) Reboot your computer.
4) Then reinstall it. The file is here: vc_redist.x86.exe
