Sony Vaio Laptop SVE1511K1E - FN Key Issue

[Tuckmando]

My HDD failed recently and after installing a new HDD and installing Windows 7 I have been unable to use my FN key to toggle the touchpad, volume, etc. Specifically the touchpad as I use a wireless mouse. I have tried to install various drivers which I have downloaded not only from Sony Support but from various mirror sites to no avail, the drivers I believe I need are:

1. Sony Firmware Extension Parser Device Driver (SODOTH)
2. Sony Shared Library (SOASSL)
3. Setting Utility Series (SOASUS)
4. VAIO Event Service (SOAVES)

However I cannot get past the first driver as it says it is not the correct version for my model, nor after 3 days of searching have I found it.
