64-Bit Office 2010 Doesn't Play Nicely with Add-Ins

Ainsley Jones

Microsoft is warning businesses off the 64-bit version of Office 2010, says seattlepi.com. Microsoft recommended companies use the 32-bit version of Office 2010 in an FAQ about its Office 2010 Technology Guarantee promotion. Transitioning from 32-bit Office to 64-bit Office could pose technical problems. According to the FAQ:

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. The 64-bit installation of Microsoft Office 2010 products will be available for users who commonly use very large documents or data set and need Excel 2010 programs to access greater than 2GB of memory. 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.


While organizations will certainly be tempted by the processing power that the 64-bit version of Office 2010 brings, Softpedia recommends decision makers consider whether they can function without the 32-bit only add-ins they are currently using.
