I have both Office 2003 and Office 365 (v15) installed.
Despite whatever I do in the default programmes it still shows Office 2003 as the default for DOCX and XLSX .
I have even tried putting the full directory path into the box but it just duplicates the icons for 2003
I need to find a way to remove completely the default and then associate only the later version of Office
Ive had a look on the MS web help but just typically gave some garble about registry - without any practical step by step
BTW - I hate Office 365 and what MS have done to it and now I hate it even more. I only have it because my clients use later versions and I need to be familiar when I am at their sites.
