I have problem and I am 100% sure Avast! Internet Security 5 causes it. After Avast! uninstall and computer restart AIK works and after Avast! install AIK not working.
Problem: Windows Automated Installation Kit mount function not working properly and I get Error 31: a device attached to the system is not functioning. And I cannot edit mounted files.
As I say in my first post I have same problem with Pro too, but program works correctly with Avast! Free. Tried disable all Avast modules, shut down Avast service, processes - no help. When I install Avast without restart computer, AIK works, but not work any more after restart. Probably Avast services works then and restrict access or something.
I have Wmware workstation too with various versions of Windows. If I don’t want change my system, I run virtual machine and I can test anything same way as my real system.
I got so many tests.
And if you need some program report about my computer or used Windows AIK full command line, just tell me.
