"The challenge with Wine, though is that it seems like
it's always two steps forward, one step back. In the process of
fixing some issues with MS Office, we improved Wine's support for
the MSI (Microsoft Installer) technology. Unfortunately, one of
those 'improvements' also made it so that no Microsoft Office
product would install. As you can imagine, that is putting a real
damper on our ability to put together a test build.
"Of course, this is not a unique challenge; Microsoft struggles
with this compatibility themselves. The Windows API is a clear
product of evolution, not intelligent design. It's origin in DOS
and the many false starts and design changes it has had through the
years pretty much guarantees that 'Windows compatibility' is very
difficult to achieve."
