Problem syncing with 32 bit outlook on 64 bit Windows 7

[ttom]

Using Bestsync 2011 32 bit on a Windows 7 32 bit machine, I was able to sync the outlook 2010 32 bit to folders on a flash drive. After upgrading to windows 7 64 bit recently, I installed Bestsync 2011 64 bit to take advantage of the extra memoray handling capability, but it cannot sync with the outlook 2011 32 bit. It says when click preview or start buttons, "Either there is no default mail client or the current mail client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client." Of course, outlook is always the default mail client on the computer. Please take a look into this. Thanks.

To synchronize with 32 bit Outlook, you must use BestSync 32 bit, on the other handle, to synchronize with 64bit Outlook, please use BestSync 64Bit.
This limit comes from the MAPI system.
