What to do if Outlook Schedule Export doesn't appear to work with Windows 7

A user of AyaNova and the Outlook Schedule Export plugin had the following issue:

When they would log into AyaNova as a scheduleable user on a certain Widows 7 computer, and run the installed Outlook Schedule Export, the AyaNova Schedule calendar in Outlook would not be created (or if already created would not be updated).

Turns out that the Windows 7 UAC was turned on, and was preventing writing from one (AyaNova) program to the other (Outlook). Once they turned off, no problems.
