Oops.

Sorry, Julie, I didn't mean that you should now download EMET in order to solve your problem.

My "solution" would only apply to you if you happened to have installed EMET before the problem with Word not opening arose. (Kind of why I said if EMET didn't ring a bell then it would not be the solution you need.)

Sorry that I didn't spell that out clearly enough - it was past midnight here and I was probably a bit tired. As a novice, I would not normally have dared to offer advice, but it did seem that we had experienced essentially the same problem and that was the way I fixed it in my case. (The only other thing I had tried was switching off and re-starting my computer - obviously - and that did not fix Word.)

Cheers
