Ok, then was it a misunderstanding from my side. I thought, I cannot upgrade to v8. I thought, my right is on v7 restricted.
But, I received from this address https://www.veeam.com/manage_licenses.html
a v8 trial version only.
I want upgrade my v7 to v8. But I thought, that is not possible because the support license.
If you need more information about my configurations, you can write me a private message and then I will send you my correct E-Mail address.
