Ok, sometimes you can't go around a Microsoft product because a crappy
site is written in Silverlight and you can't go without it.
These steps install a modified version of Wine and configure it so that
the site which I needed.
Software called Magister used on a School website to monitor childrens
progress worked oke for me on Ubuntu 14.04
$ sudo apt-get install python-software-properties
$ sudo add-apt-repository ppa:pipelight/stable
$ sudo apt-get update
$ sudo apt-get install pipelight
$ sudo pipelight-plugin --update
For system wide setting:
$ sudo pipelight-plugin --enable silverlight
For current user only:
$ pipelight-plugin --enable silverlight
Please note that only Firefox browser will work, since Chrome version
>34 doesn't support the NSAPI anymore which this plugin uses.
