While creating a schema using the ‘Generate Schemas’ wizard I noticed that the ‘Well Formed XML’ and ‘DTD’ wizards are not loaded by default. If you try and use one you’ll received the following error message:
WFX to XSD schema generation module is not installed. Execute C:\Program Files\Microsoft BizTalk Server 2006\SDK\Utilities\Schema Generator\InstallWFX.vbs to install the WFX to XSD schema generation module.
To resolve this issue, simply run the aforementioned VB script; you’ll also need to run the InstallDTD.vbs script to add DTD support.
Support is available when you re-run the wizard - no need to restart VS.
I got the same issue after I installed BizTalk 2006 R2 in a Vista macine. I did executed the scripts, but it could’nt help. I copied the two DLLs from the same folder and pasted in /Developer Tools/Schema Editor Extensions…its working now
that warked for me too, i run it in windows vista, thanx saravanan
