I will try and help as this an old thread or give it a bump.
Has the AVR been disconnected and then reconnect to the PC.
The PC recognizes that there is New Hard ware and is probably referring to AVER.
It says Can Windows connect to Windows Update to search for Software ?
Options Click (Yes this time only),
Others may come to your rescue now its been brought back.
What is your OS and make of AVER and Processor speed?
