4.) Why run as administrator, what should you watch out for?
Why as an administrator?
Many applications have been developed for Windows XP, these work with modern Windows 11, 10, in most cases. However, during the Windows XP era, almost every Windows PC was run with an administrator account at all times.
Many programs have also been developed in such a way that you need and have to have administrator access, mostly no registry entries can be made, which leads to problems, such as system-specific access!
If you have 16-bit programs, they will no longer work under Windows 11 because Windows 11 is only available as 64-bit versions. The 64-bit version of Windows just doesn't include the WOW16 mode that allows 16-bit to run.
Only the error message appears: "This application cannot be executed on your PC"
PS: In time you should look for alternative solutions / programs!
