Above error shows up during Index creation on KM section of the portal.

Checked the TREX Admin tool for Http connection . Pop up Error saying "IIS not installed. Configuration of Http communication not possible ".

Environment : TREX 7.1 revision 43 on Windows 2003 64 Bit platform.

During installation of standalone TREX , there were no option to select "http server".

Please suggest, if i am missing some thing in the setup or configuration here.

Thanks in advance .

1.) You need to make sure that the server you are installing TREX on, also has a Web Server. In your case, Internet Information Services (IIS 6.0) which comes with Windows Server 2003. Once this is installed make sure that it is working (http://hostname or IP).

2.) TREX 7.1 Rev 43 is very mature and does not involve many steps during installation. Your only option is to choose whether you want to install it or not.

3.) Setup of the "http connection" or "ABAP connection" is done after TREX installation. This is done straight from TREX Administrator.

Here is my suggestion:

1.) Install IIS 6.0 (

2.) Reinstalling of TREX is higly recommended but you can try it with the current installation.

3.) Open up TREX Administrator (trexadmin.bat) and proceed with create IIS Websites for TREX 7.10. The steps are located under the heading "Configuring the TREX Web Server" in the installation document.

4.) After this, go on with Indexing.
