I have Elements 9 and I bought the update to Elements 10.
The Software has been registered correctly and the Elicenser is updated
All various parts have been installed, only Elements 10 does not install
It says āSteinberg Cubase Elements 10 is not installedā and there is no way to change it.
I have updated from 7 to 8 to 9 and never had any issue.
There is no reason to uninstall version 9. Iād strongly advise against uninstalling it until you are happy with version 10.
The other point is valid though. It sounds as though you are trying to upgrade using the 10.0.10 update not the full installer for version 10(this why youāre getting the error message that you quoted).
The licence and the upgrade are 2 things. You need an update licence and a full installer. What fails. The update of the licence or the install of the program.
