By default, the Webserver that is shipped part of the FileCloud installation runs as a normal process. If the user running the application logs out the application will exit. To prevent this, you can run FileCloud Webserver as a service.
Install as a Service
Click on "Make Service" link in the Control Panel. It will be installed as a service. You can then click on "Start" to start the service.
Alternate way to install as a service, open an administrator command prompt
Remove Apache Service
