Diablo 3 updating blizzard update agent

10# Unexpected Decryption Error This means installation files are corrupted.

I've tried several things, running wow as administrator, and my friend showing me how to delete the folder, but it didn't change anything. Every time I open my launcher that little window pops up, however I've never had it hang.9# Tome Error If you receive this error while installation, there is probably something wrong with the installation files.Restart Diablo 3 downloader and let it finish; it should start installer itself.But at least it's moved on to Updating the Blizzard Update Agent, so I suppose this is progress?Diablo 3 launched on PC today and if you were expecting a smooth launch day ride, you are in it for a surprise.
