I have worked so far with Office 97, XP, 2000 and 2003, renewed with the switch to a new computer and the software. The product has gotten better, you have to get used to the new products but only. The installation of the PKC-version (Product Key Card) may have been a bit complicated I succeeded only after a third attempt ohn help from Microsoft. The price is very high for a normal consumer, unfortunately there are no previous versions as with the ability to upgrade more, hence the 4 points. One thing I noticed when Outlook there are unfortunately no points for securing their own files, but this was present in the previous versions. Attention in the adoption of ACCESS databases no calendar ActiveX control may be present, because this element is available in the 64-bit version and no longer, therefore, a takeover of the database is not possible and will generate an error.
