There have been messages on the forum and via email in the past few weeks about an issue that occurs with MS Word Template Builder. It appears that the latest MSOffice patch breaks all versions of the Template Builder prior to 184.108.40.206. You'll get an error similar to:
'The macro cannot be found or has been disabled'
It actually appears to not only break our plugin but any VBA based code that might be embedded inside MSWord.
Rather than re-regurgitate the current work around (we're assuming MS will get a fix out at some point) Im pointing you to Damir's blog entry here.
Jim from S&C Electric let me know of another solution:
We had a similar issue.
Our fix was the find the files with exd extensions and change the name so they were not available.
Maybe this will help.
