Common problems

A .btm file opens as XML text
An editor association overrides the extension. Use Open With…, choose BizTalk Map Viewer, then Configure default editor for '*.btm'. Or remove the *.btm entry from workbench.editorAssociations.
Invalid BTM XML: …
The file is not well-formed XML. Open it in the Text Editor, fix the error shown, and the view updates.
This file is not a BizTalk mapsource document.
The root element is not mapsource. The viewer only reads BizTalk Mapper .btm files, not XSLT or Data Mapper files.
No map pages found.
The file has no Page elements under Pages, so there are no links to show. The source and target cards are still filled in.
No mappings match this filter.
Clear the filter box, or check that you are on the right page.
The extension does not install
It needs VS Code 1.85 or later. Check Help › About.
