Once you confirm that your computer will support the update we can trouble shoot.
Are you doing a clean install using the Windows Media Creation tool, or using the Windows Update feature?
Take a look in Update history to see the update failures have been logged there. Depending on the point in the update process they may not be.
If you do get other error codes we can try to suggest fixes for them.
