DiffEngineX is a desktop application that loads two Microsoft Excel workbooks from the filesystem and reports on the differences between them. It is not an Excel add-in.
DiffEngineX has been tested on Windows 8 Release Candidate and it has been found to work.
We currently offer three different size downloads for DiffEngineX. Only the largest size one that has been built against the latest Microsoft libraries and runtimes will successfully install on Windows 8. On our download web page it is labelled as being the "newest build" one.
All our DiffEngineX downloads will work on Windows 7, Vista, Windows XP and Windows Server. Microsoft Excel (or Office) is a prerequisite.
