There is a problem with a number of word documents, when opening them they open with a normal.dot template that does not exist called 'infopack.dot'

I have not been able to find why or how they are picking up this default normal.dot template. Other docs are fine.

If I change them to the original 'normal.dot' all is fine. However the issue is that there are so many docs.

Is the template hard-coded into word documents? Does anyone know a way around this?

Any assistance appreciated.
