An error has occurred. Unspecified error

I am currently on Windows Vista Home Premium 32 bit and I have bought and downloaded Windows 7 Pro 64 bit.

I have used the upgrade adviser and it says:

Welcome, Black Fenix!

In order to upgrade from a 32 bit OS to a 64 bit OS, you have to do a custom installation. There is no upgrade path when moving to a 64 bit OS. I highly recommend you take a look here:

Clean Install Windows 7

If you have upgrade media, you can still do a clean install:

Thanks.

Unfortunately I am not a very tech savvy person and have honestly got no idea but from what I understand the three options given there are for when you boot up the comp however all I have is an .exe file.

Where did you download your upgrade from? Is this a student download? If so, you can make a DVD:
