Internet Information Server (IIS) needs to be installed in order to run TX Text Control in server mode. It can be run on a dedicated server, or by simply activating IIS on the developer's computer. This way, a server application can be developed and tested on the same computer, without requiring access to a seperate server.
At some point an application most likely is to be transfered to a 'real', dedicated server. The following steps are required to transfer your TX Text Control license to that server.
Note that the license agreement entitles you to have TX Text Control installed on your local computer and a single server at the same time, so that you may continue maintaining your application with a local copy of TX Text Control.
