It seems like MS Office 2008 crashes after macOS Sierra 10.12.2 or couldn’t install with El Capitan, I accidentally discovered how to get it working. While experimenting macOS Sierra on an external USB drive before restoring it to the internal hard drive, I opened the hard drive Word App and it didn’t crash, just asked me to fill in name and register as a new program, filled in everything, when it’s done and everything opens as it was working before. I copy the whole directory from the internal hard drive to the applications folder of the USB external hard drive to confirm, execute the Word App from the Applications folder and it works just like in Yosemite.
