I have an old document with equations in it and I need to edit them. You can install the 32-bit and 64-bit versions of Office side-by-side, but I recommend instead creating a simple VM (virtual-machine) to install an older 'good' version of 32-bit Office to act as a format-bridge (Office 2010 is my personal favourite).Hello.

NET Framework, and now is the basis for WinMD/WinRT in Windows 8 and Windows 10 - it's come a long way).Īnyway, because these components are binary programs in their own right, it means they must match the instruction-set architecture of the host process.
