In the last post I questioned the availability of the MS Office file property handler on systems without MS Office installed. I just discovered that there is a default OLE Document property handler that ships with windows (7 at least) that will do the same thing, in fact I will use this on my system instead of the MS Office one. So from the last post just replace all references to:
{97e467b4-98c6-4f19-9588-161b7773d6f6}
with:
{8d80504a-0826-40c5-97e1-ebc68f953792}
and it will work just the same but without any dependence on MS Office.
Oh, and by the way, it’s always a good idea to reboot when you’re done, you can get unpredictable results until you do so.
