I am unable to install a game. A vague message pops up after I accept the terms and agreements that says "An unexpected decryption error has occurred". There is no code or error number associated to the message.

This page helped me quite a bit with the few issues I had.

Quote from that site about this issue:

Error 108 Similar to “An unexpected decryption error occurred”, the error 108 can be caused by corrupted, damaged or incomplete installation files. This can often times be caused by closing the downloader early. Though the downloader may show 100%, please allow some time for it to fully complete.

You may be able to fix this by running the downloader and pointing it to the same saved location so that it may scan and download any missing files.

If the problem persists, let us know.

you have to start all over again try this,
go to your folder where battle.net and delete it, if you cant find it then
Ctrl + alt + delt = then start task manager right click on agent.exe and then open file location
end process and also delete file battle.net it's usually a hidden file with in C:
right click on the Diablo-III-Setup-enUS from your download file properties then compatibility then select run this program windows xp ( service pack 3)
if dont work try the same method but run as admin with the windows x[ service 3
if the first try didnt work make sure you delete battle.net ( the entire folder ) leave nothing behind start new
hope this help
god bless the warrior class.
