Q:  I just changed computers and my email outlook is not working. What version of Microsoft Office 365 do I download to work with CertiflexDimension Ultra?

A:  We recommend using the 32-bit version of Microsoft Office. In fact, Microsoft recommends the 32-bit version of Office for most users, because it’s more compatible with most other applications, especially third-party add-ins. This is why the 32-bit version of Office is installed by default, even on 64-bit Windows operating systems. On these systems, the 32-bit Office client is supported as a Windows-32-on-Windows-64 (WOW64) installation. WOW64 is the x86 emulator that enables 32-bit Windows-based applications to run seamlessly on 64-bit Windows systems. This lets users continue to use existing Microsoft ActiveX Controls and COM add-ins with 32-bit Office.

The feature sets of 32-bit and 64-bit versions of office are similar except in cases where You’re working with large data sets, like enterprise-scale Excel workbooks with complex calculations, many pivot tables, data connections to external databases, and so on. The 64-bit version of Office may perform better in these cases. (More information can be found at Microsoft’s website at this link https://technet.microsoft.com/en-us/library/ee681792.aspx )

After verifying that you have the 32-bit version of Office (please see below), you will need to update the registry key as well. Your IT department can assist you with that. A copy of the key can be found at this link Outlook MAPI key
