Problems when uploading games to OneDrive

I am doing a project where I need to upload my finished games onto OneDrive to submit them. I zip my two finished packaged games into a .zip file. However when I download this file back off OneDrive to see what it’s like on their end, they can’t be opened on the version I downloaded back from OneDrive, meaning they won’t be able to play on their end. I have attached a screenshot showing how the original games appear in the folder (Top one) compared to the one from OneDrive (Bottom one). I have also shown the respective error messages when attempting to open these files. Any help would be much appreciated!

Any use?

No luck with that sorry. Thanks for the response though!
