Google Calendar sync in Windows 7 64-bit

"Google Sync is not compatible with 64-bit system, as mentioned in compatibility

Compatibility

Currently, Google Calendar Sync is only compatible with Microsoft
Outlook versions 2003 and 2007, and
operating systems Windows XP and
Windows Vista.
Windows XP 64-bit Edition is not compatible with Google Calendar Sync
at this time

Although they mention Windows XP 64-bit is not compatible, this probably holds good for successive 64-bit versions, for the time being.

An alternative might be SyncMyCal"

"Too late answer, but what you have to do to solve it is to repair your office/outlook install, and after that, everything should work.
I'm using it in 7 x64 and works perfectly."
