Can I install Microsoft Office 2007 into more than one PC?

I wanted to know if I would be able to install MS Office 2007 into more than one computer or will I be able to install MS Office 2007 into one computer but install it many times? Since there might be some issues in the computer sometimes, so I will need to prepare it and if I lost the Office 2007 program, then will I be able to still install it again? Thanks.

Yes, you will be able to reinstall it on one machine as many times you would want, whether you can install on more then one computer it will depend on what version you have purchased, and what your EULA says.
