Hi there. Are you using Windows 11, or have upgraded to Windows 11 by chance? If so, this is likely a backwards compatibility issue with Microsoft and the much older Itch.io version of Jav-It. You can get around this by running on a lower version of Windows, Using a VM to run Linux, or using the Patreon version which bypasses this issue.
Additionally, for Windows you can try installing the latest visual C++ re-disputable. In some instances, Windows will have issues when this Microsoft library isn't up to date, yet it won't tell the user (in an obvious way) as such. Here is a link you can try:
