Hi,
1)Check the access rights of the “C:\Documents and Settings\All Users\Application Data\AVAST Software\Administration Console” folder, are you logged with administration account or not?
2)Try to put here the license.avastlic file by copy and paste.
3)

Have you tryed to insert the licese during the console install?
4)Wich version of console are you running? Can you check if it’s the lastest one (1.1.132.15)?
