Amazon Web Services Developer Community : Client.AuthFailure ...Hi, I'm getting the following error when I attempt to issue a ec2-describe-images command .. Client.AuthFailure: AWS was not able to validate the provided access credentials I'm running under Windows XP. JRE 1.5.0_08. I've registered for EC2 and generated/downloaded a cert. I believe I've set up the required environment variables and made the changes suggested in the Typo in Windows ec2-cmd.
