My company laptop has died and my personal one only has the Microsoft Office "starter" package on it. Apparently the "full" package is already installed but needs a licence key. I can find no way of checking which version of Office 2010 is installed though (home, professional etc). I need the full version of Excel as I use VBA and other features the basic one doesn't have. What's the cheapest way of updating it? Going direct to Microsoft I'm offered: Home and Student (This has all the programs I need assuming[i/] it is a full version of Excel.) £99. Small business (Has some extra guff I don't need) £190 Professional (More guff I don't need plus Access) £300 (If I needed a database I don't think Access would be my starting point) Excel to buy on its own is £110. I can find product keys for less but how to tell if they are bogus? Here's one for example: http://www.windows7validation.co.uk/index.asp?function=CART&ECD=2375&productid=10 Cheap but is it OK? All help gratefully received.
