I have transferred the licenses successfully over to a new computer from an old dying computer. I have no original disks and was only able to download trial which I wanted to just attach the license to the software. I not sure of the next step

The original registration belongs to prior employee as well. So when is use license manager and log n thorough this service it said to contact support and I am brought to this site blog

 Hi,

from which licence you talk?
Which Software should be licenced?

Which Licence Manager you use?

Which messages You get and which licence displayed in the licencemanager (you transfer the licence with licence manager?)

Regards

Christoph
