Error 1006

i keep getting same message error when i try opening avast 4.5…error…An error 1006(000003EE) has occured…Last performed operation was: opening the sel-extract archive…i do what it suggests but to no avail…can someone help me?

Give a repair of Avast a try.

Can you tell me how i go about doing that?
