TTI worksheets are built and tested using the latest Windows "desktop" version of Microsoft Excel 2016.
Use of the TTI Suite in a Microsoft Windows environment requires "desktop" Microsoft Excel 2010, 2013, or 2016.
Use of the TTI Suite in a Mac environment requires "desktop" Microsoft Excel 2016.
Use of the TTI Suite in other environments (e.g. Excel "online", Android, iOS) is possible, but you may experience formatting and performance anomalies based on limitations of the program.
We recommend that your monitors use a resolution of 1920x1080 or greater to ensure an adequate viewing area. For maximum stability, we recommend the latest Microsoft Office service packs.
