Wine’s pretty good these days. On its own it can install and run programs like Microsoft Office under Linux. This is thanks, in part, to contributions made to the Wine project from the Codeweavers gang.
Their flagship product, Crossover, is a commercial product based on Wine which lets you install many products from the Microsoft platform.
Mike sent me an email that for the next 24 hours or so, Codeweavers are offering Crossover Professional and Crossover Games for FREE.
Update: You don’t need to register your email, just download the version that you want.
Oh, and there’s an OS X version too.
No need to register anything to get the free download – you can ignore the bit at the start of the page and just grab a download.
Oh yeah, thanks Mike.
