Cubase Le 10 installation

I have purchased audient id4 with this Cubase Le comes. I installed first time successfully.
But after Formatting the windows machine I can’t reinstall the same.I have followed all the instructions but fail to install. Please help.

Hi and welcome to the forum,

Did it fail during the installation or during the activation? If the second is the case, go thru the Reactivation process, please.
