Note about upgrading to GDevelop Beta 93 from beta 89 or older
Latest GDevelop versions are updating the internal framework on which GDevelop editor is built. It seems that the auto-update on Windows could be broken if you try to update from Beta 89 (or older) to latest betas.
The solution is to uninstall GDevelop first and then download GDevelop beta 93 from the website.
