Check_MK Werk 5501: cmk-update-agent: Fix mistaken server response for Windows Agent Updater

ID: 5501 Title: cmk-update-agent: Fix mistaken server response for Windows Agent Updater Component: agents Level: 1 Class: Bug fix Version: 1.6.0i1 Due to a bug in the handling of the Check_MK server response, a valid downloaded MSI-packaged agent updater can be mistaken as a "login failed" response. Instead of updating the Windows Agent, the agent updater would display the error message "ERROR: Cannot authenticate, invalid user/passwort/secret." and abort. In order to restore funtionality to the Agent Updater, please uninstall the Windows Agent on the affected hosts and reinstall with a newly baked MSI-package.
