Portable Microsoft Office 2007 is a self-contained version of the popular office suite that can be run from a USB drive or other portable device. This means that you can carry your office applications, including Word, Excel, PowerPoint, and more, with you on the go, without having to install them on every computer you use.
Portable versions are created using tools like , Cameyo , or VMware vCenter Converter to virtualize registry keys and file dependencies. These tools can repackage 32-bit apps to run on 64-bit Windows via WoW64 (Windows-on-Windows 64-bit), but the app remains 32-bit internally.
The first 64-bit version of Microsoft Office was Office 2010 . Office 2007 was designed exclusively for 32-bit processors, though it could run on 64-bit Windows via the WOW64 (Windows-on-Windows 64) compatibility layer.
