V5 Sample Programs Errors

My students are using the movement teplate in Modkit.

Some of them get compile errors and the error log mentions math.h?

But all they have done is download template (unaltered) to their brain!

If they move to a different computer, it works.
But it has happened on 4 of my 13 computers??

What type of operating system are you using?

Try uninstalling all parts of Modkit (and VCS if involved - not familiar with it), ensure computer’s OS is updated. Restart computer. Run freshly downloaded Modkit installer. And VCS if applicable.
