Trouble to install ChemistryAddinforWordBeta2.Setup.msi.

Hello, I am trying to download chem4word. After clicking on its icon in the downloads folder I am getting the following message: there is no default application specified for this document. How do I make it work? This program is from the website Free tools for teachers - Partners in Learning Network

Thank you.

This is a Windows Installer file (.MSI). In other words, software for Windows. Assuming you're using a Mac, you won't be able to use this software.

You may be able to run it by either installing Windows via virtualization or Boot Camp, or perhaps with WINE or Crossover.

Thank you cwa107 for the quick response! I didn't know .MSI is a Windowns Installer file.
