Just to clear this question up.
I purchased the 9.5 Elements to Elements 10 upgrade.
I opened the previously downloaded Full Purchased Elements 10 downloaded file that was installed on another computer.
The program installed as expected. I opened Cubase Elements 10. It requested the activation code which I entered.
The program updated the License and Cubase 10 Elements opened.
So I saved 10 hours stress going through the download process by using the same disk image twice.
Very happy
Thank you for you helping
