Hi Majdi Al-Amili,
First of all, is this software installed by you or by another user? If you installed it, you theoretically have sufficient access rights.
As you described in your original post, you wanted to change the owner of the file, but failed. Now I suggest you try changing the permissions on that folder. Right-click the folder > Properties > Security tab > Edit, then click your username, then check "Allow" to the right of "Full control" in Permission for Users, then press Enter to confirm, if there is any prompt, you can be ignored first.
It is then recommended that you try your copying operation while exiting the security software and exiting the game. Or you can try reinstalling/overinstalling the app.
Is it possible to do a copy operation in another directory in C:\Program Files (x86)? I suggest you try it.
Or you can try the copy operation in safe mode. Because Safe Mode enables a minimum number of additional services or apps to rule out issues caused by personalized settings and third-party apps. You can click Start your PC in safe mode in Windows (microsoft.com) to view the specific operation steps.
