licence problem

Hello, I use windows 8

when I want to enter my licence to activate I have this message :

Probleme pour Joindre le serveur de licences:
Imposible de générer une classe temporaire (result=1).
error CS0016: Impossible d’écrire dans le fichier sortie ‘c:\Users\media u\AppData\Local\Temp\6mcuc2k8z.dll’ – ‘Could not execute CVTRES.EXE.’

Can you help me to complete the activation ?


Hi, it says that you can write data to this folder c:\Users\media u\AppData\Local\Temp\6mcuc2k8z.dll do you use eM Client on Windows account with admin rights?



Thank you for the answer

Yes I have admin rights with windows 8

try to patch your .NEt framework by using this…

if it will not help then update it to latest version…
