I've been getting a similar error over the last couple of days when installing or updating applications. Currently trying to install After effects and it will progress 1 or 2% and then throw the 'Installation failed' error with a learn more link that says 'Unable to reach adobe servers. Please check you internet connectivity, firewall settings and then try again.' error. If I hit retry it will progress another 1 or 2% and then stop again.
Is there currently an issue with Adobe servers?
