Guys, like somebody said previously, you should have 2 or even 3 different versions of internet explorer installed onto your windows 7.
Goto your bottom right hand corner and click start, then search for 'internet explorer'.
I have 3 options that come up:
Internet explorer
Internet explorer (64bit)
Internet explorer (No Add-Ons)
The first internet explorer is the 32bit version.
Now just drag that icon onto your shortcuts and you can now choose to run 32bit, 64bit or no add-ons version of internet explorer.
Hope this helps.
Let me know as I spent a while seaching around to find a solution but managed to work it out with a little help.
