When I copied files from a Windows 2012 server to some Windows 7 PCs, it often prompts the error 0x80090006: Invalid signature.
Once I clicked ‘Try Again’ button, the copying progress will resume. I tried on 3 ‘Windows 7’ computers and 1 ‘Windows Server 2008 R2 with SP1’ computer, it promoted the same error. The error was not always prompted, sometimes I could not reproduce this error in a whole day.
Is there anyone knows what causes this error and how to solve it?
