Note that the first few images are from myself, and the rest are from here since I don't have a MS Office 2010 CD.
The following tutorial also works in Ubuntu 12.10.
Download PlayOnLinux using the commands:
wget -q "http://deb.playonlinux.com/public.gpg" -O- | sudo apt-key add -
sudo wget http://deb.playonlinux.com/playonlinux_precise.list -O
sudo apt-get update
sudo apt-get install playonlinux
Search for the Microsoft Office version you want to install (in our case, it's MS Office 2010).
Choose Other. I'll assume that you have your MS Office 2010 CD.
Insert your CD and type
/media/cdrom in the blank space. Replace
cdrom with the name of the CD. Then click next and MS Office 2010 will be installed!
Although you can install MS Office, I recommend using LibreOffice (which is installed by default). It's a free Office Suite that is compatible with all your office files.
