Yes, let me try to help:
Do you have an old windows version? (8 / lower?)
Games made with Unity 6 require "Windows 10 version 21H1 (build 19043) or newer",
that might be the issue.
If that's the case then you can
1. If you don't want to upgrade you can run the android version of the game using "Bluestacks" https://www.bluestacks.com/
or
2. Upgrade windows to latest windows 10 version
If that's not hte case:
1. Have you extracted the game to a sperate folder first?
2. Also does the free version work to you?
3. Is it by any chance placed in a folder with path that has non-english words or spaces or symbols? (Maybe throw the folder onto your dekstop)
4. Are you sure you have enough free space on your machine?
5. Are my other games not working? (You can play their free versions to test)
Other desperate measures if you don't want to do any of those:
1. Download the game directly to the "C:\" folder
2. Right click on the Sunkissed.exe > run as administrator
