The Cloud App Launcher failed to start even if the launcher has already been installed.
Cause:
The client machine has third-party firewall tool, such as Sophos. The process of Sophos such as swi_filter.exe and swi_service.exe block the access to the launcher URL.
Solution:
Configure the firewall to allow access to the following IP address and port numbers:
http://127.0.0.1:26568
http://127.0.0.1:26569
