I wish to install wine how do i do it

Linux does not natively run any windows exe files.
In order to run windows files you will have to run them with a compatibility layer called Wine.

To install wine in Ubuntu

Please first enable the universe repository:

Open System → Administration → Software sources → [ Tab Ubuntu software ]
enable "Community Maintained open source software (universe)"
Close and confirm the repository reload.

Then open a Terminal from the menu Applications → Accessories → Terminal and type:

sudo aptitude update
sudo aptitude install wine

give your user password when requested, you don't see nothing when you type it, then press enter.

Then there are a lot of howto on the net:
