I did a bit of googling and this is what I came up with.
That error message seems related to 64-bit systems. And based on the path you gave jobeard you must be running 64 bit Win 7.
On the one hand, it might be the result of some severe system problem ( I even saw a MS kb about that msg due to 32-bit support turned off but that was about a 64-bit Windows Server, not a Win 7 PC)
On the other hand, you mentioned following a thread by Broni. (I think I found that thread too).

You might be best to first rule out malware. That means creating
your own malware thread! (Start with the steps provided in the sticky at the start of the malware forum) fyi..You can't follow malware advice for someone else. You need to create your own thread and follow the advice specific to you.
If the malware people think it's a systems problem, they'll send you back here to the non-malware forums for help
/* EDIT */
p.s. Whether turns out malware or maybe worse if a systems issue, it sounds (to me) like alot of work. So if you also have the option of a recovery partition (back to factory default) or a Windows re-install, that may turn out to be the "shortest distance between two points". But in any case, is up to you.
