Choose between the 32-bit and 64-bit versions of Office
As mentioned before, 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. For an add-in to work with the 64-bit version of Office, it needs to be recompiled by the developer specifically for the 64-bit version of Office. In some cases the developer also needs to make some specific changes for 64-bit support or needs to wait for specific libraries, that the add-in relies on, to be recompiled for 64-bit.
Can i run 32-bit and 64-bit versions of Office on the same computer – No this is not possible. Office doesn’t support running side-by-side installations of 64-bit and 32-bit versions of Office. For example, you can’t install Office 2010 32-bit side-by-side with Office 2013 64-bit. This applies to both Windows Installer (MSI) and Click-to-Run installations of Office 2013. If you try to do this, you’ll receive an error message and be prevented from continuing.
