The installation files for the Web Services interface are included in the ITP/Server installation folder, in the folder ITP Server\Apis\Web Services. Copy this folder to a suitable location outside of the ITP/Server installation folder.
Note:
Although it is possible to install the Web Services interface using the Web Services folder in the ITP/Server installation folder, this is not recommended. The reason for this is that upgrading the ITP/Server installation will overwrite the configuration.
