I recently purchased ShowBIZ 2.0. Can I update to the latest version for free?
I've searched the application and it appears that ArcSoft ShowBiz appears only on the Microsoft Store. There is no other place where you can get it. Secondly, the ArcSoft website contains a page where you can see all the updates available.
This is the only way to obtain updates for the application. You can try the Microsoft Store option as well, but I don't think it will work this way.
