The download of the TTI Suite is a zip file and generally only takes 1 to 2 minutes. Detailed download instructions are available here. Beyond extracting the worksheets after download, no installation is needed.
Our suggested practice would be that one person (and one backup) receive the updates, and make them available within your firm. This is normally done by extracting the package to a shared network drive. We also recommend making the folder “Read only” to prevent accidentally overrides of the master solutions.
Depending on the software you use, you may also update client templates in your document management software.
