.docm "edit this file"?

Hi Folks,

When viewing files in a workspace, Word files ending in .docx have the capability of "Edit this file" but files ending in .docm do not. I tried adding the extension thru the administration console "Extensions" section but it says: "This plugin is missing the install.xml file." I looked in the Vibe Resource Library but could not find anything to help with this. Can anyone tell me how to give the Word and Excel macro documents the Edit this file feature?

Thanks,
Toney.
