think-cell is a Microsoft Office add-in for PowerPoint and Excel, which integrates with these applications to make it easier to build and visualize simple or complex graphs. Iscte – Instituto Universitário de Lisboa is a partner university, which allows its students, staff and teachers to enjoy unlimited free use of the think-cell software.

Since these are free versions that were made available by the company that represents the software, their use and installation is the exclusive responsibility of the users, and therefore there is no support or technical support from SIIC.
