I came accross a situation where default schema templates were missing after BizTalk Server 2006 R2 installation. After some googling I didn’t find any solution out of it. MicrosoftEdiXSDTemplates.exe is a self extracting archive that have thousand of EDI schema templates ready to use. It can be found in
%programfiles%\Microsoft BizTalk Server 2006\XSD_Schema\EDI directory. But If you don’t find this directory and MicrosoftEdiXSDTemplates.exe file, this means some thing is wrong.
I came to know that order of BizTalk installation does matter to resolve this issue. Just verify whether you installed VS 2005 before BTS installation. In my case I installed BizTalk Server 2006 R2 prior to installing Visual Studio 2005. Fix is very simple. Just Modify BizTalk Installation and check Developer Tools and SDK check box during installation. After Installation you will be able to locate MicrosoftEdiXSDTemplates.exe in %programfiles%\Microsoft BizTalk Server 2006\XSD_Schema\EDI directory.
