Microsoft is advising its customers to install the 32-bit, rather than the 64-bit, version of Office 2010.
The advice is tucked away in an FAQ about the Office 2010 Tech Guarantee programme, which will ensure that buyers of Office 2007 will get a free upgrade to the new Office suite when its launched.
"We strongly recommend most users install 32-bit version of Office 2010 on both 32 and 64-bit operating systems because currently many common add-ins for Office will not function in the 64-bit edition," Microsoft warns.

"There may be technical issues with the 64-bit version and in order to install a 64-bit version of Office 2010 product users must have a 64-bit supported operating system on their PC," Microsoft adds.
Even some of Microsoft's own Office plugins are not yet compatible with the 64-bit software, including the Outlook Social Connector, which hooks the software into social networks such as Facebook. Third party plugins from LinkedIn and Symantec are also 32-bit only.
Microsoft's missive echoes the advice of PC Pro's Real World Computing expert Simon Jones, who has been advising readers to stick to the 32-bit version of Office 2010 for many months.
From around the web
How are we ever going to move into a completely 64bit world when Microsoft can't even ready 64bit compatible versions of their own Office plugins?
Tech firms as a whole need to pull their collective fingers out if 64bit is to ever take off en masse.

Very sensible advice
In other words: "If you need 64 bit functionality, get that one. Otherwise, you don't need 64 bit functionality"
I know we all like bigger numbers but we don't need 64 bit precision for Clippy to help us write a letter.

addins
"many common add-ins for Office"
What about an add-in that gives native support, at OS level, for importing of .pcx graphics and thumbnail viewing of .pcx in Windows Explorer?
