I just bought (and already paid) a AVG Internet Security product and I several times tried unsuccessfully to install it on my PC (I have an OS Windows 10 64-bit )
The AVG application give me back a message of error code "0x00C0070643 - Description: Event exec_finished", occurred during the initialization". How can I fix it?
thanks,
Andrea Catalano

Yes, Andrea. You are right.
