TextWorks 9.0 and older: Maintain Thesaurus displays "Unable to access the thesaurus"

For DB/TextWorks and CS/TextWorks 9.0 and earlier...

On systems where Internet Explorer 7.0 has been installed, choosing Maintain>Maintain Thesaurus from the Textworks menu will display:

Unable to access the thesaurus.

The recommended fix for this issue is to upgrade to TextWorks 10.0 or later, then run Setup Workstation from each workstation that has IE 7.0 installed. This process will create the necessary registry key on the workstation, so this message doesn't appear, and Maintain Thesaurus works properly.

If upgrading is impractical for some reason, the following registry key needs to be created manually. (Replace dbtext32.exe with inmcsrv.exe for Content Server systems.)
