oox39,
It would help if you be more specific, and detailed on how to install and update Arma Studio on the download page or GitHub page, and the potential install issue(s) i.e. the issue below. The solution to the problem below is in this thread that you posted earlier on February 28. It wasn't obvious and it's not the same error below, but it fixed the problem.
Also, more documentation on Arma Studio would help a lot too! Thanks for the good work so far!
