This software package installs the latest version of Drafting Assistant as an add-in to Microsoft® Word.

Release Notes:

  • Enhancement – New automatic updating option provides increased frequency of improvements and bug fixes without manual installation.
  • Enhancement – Deal Proof can Ignore Schedules, Exhibits, Appendices, Attachments and Annexes, which is checked by default in Deal Proof Settings for more targeted analysis.
  • Enhancement – Deal Proof can Identify Defined Terms Outside of Definition Section, which is unchecked by default in Deal Proof Settings for more targeted analysis.
  • Enhancement – Deal Proof pulls together key parties, dates, monetary values and governing law in new Key Terms section of report.
  • Enhancement – Deal Proof References adds Monetary Values and a new Numeration flag for currency text/symbol mismatch.
  • Enhancement – Deal Proof cross reference dropdown can link correct references for auto-numbered documents.
  • Enhancement – Condensed footer allows more vertical working space in side panel.
  • Bug Fix – Certain modifier keys (including “alt” key commands) didn’t work when Drafting Assistant was open.  Now they will.
  • Bug Fix – Some antivirus programs raised an alert upon add-in shutdown and blocked temp file cleanup process.  Now this logic is performed within a Word process that antivirus programs should be aware of.
  • Bug Fix – Certain files deployed in the roaming user profile folder could prevent Drafting Assistant from running normally if this folder was on a remote file share.  Now Drafting Assistant uses a local folder. 
  • Bug Fix – Deal Proof did not work properly if Windows locale setting used a comma as a decimal separator.  This is fixed.
