Bitness in Office version from command line
Is there a supported way to tell quickly via the command line quickly which version of Office is installed (x64 or 32). It would be great if there is a way to tell regardless of if Outlook is installed.

Hi,

As far as I know, the valued of Bitness is stored in registry keys. We can use PowerShell to query the value:

Then, if you want to check regardless of if Outlook is installed, we might to use filter the product code GUID:

When you install the Office 2013 suite or one of the stand-alone Office 2013 programs, one or more product codes, or GUIDs, are created in the following registry subkey: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall If you install a 32-bit version of Office 2013 on a 64-bit version of Windows, the GUIDs are created in the following registry subkey: HKEY_LOCAL_MACHINE \Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall Each GUID uses the following format:

{BRMMmmmm-PPPP-LLLL-p000-D000000FF1CE}

001A represent Microsoft Outlook 2013

Hope it's helpful.
