Hi, Stephan.
We're here to help. You need not to download the setup file to repair the already installed program. Please click this link for instructions to repair.
Could you let us know why are you trying to repair AVG?
To repair AVG Antivirus i should install AVG_Antivirus_739, but it says error 0xe0010058. What is it?
AVG Antivirus (evtl. AVG Antivirus 2015) says: "Sie sind nicht vollständig geschützt" and "reparieren", the component "Computer" says "Aktualisierung erforderlich", the same with "Web" and "Identität".
Stephan, could you provide the screenshot of AVG Antivirus window here?
