Here are a few things that are not all may consciously and for the use of Outlook 2010 and Office 2010 (only Home ???) are relevant: - The 64-bit version can not use a 32-bit version, for example, Office / Outlook are combined - The 64-bit version does not seem to be faster, but prevents synchronization with Windows Mobile, and - The "send to email recipient" from other programs is no longer possible. I therefore uninstalled everything again and filled with the 32bit version.
