For some political reason, as described here, Codeweaver is giving away their professional version of Crossover Mac and and Crossover Linux for free. This however is only valid for those who registers for the products today.

Crossover Mac and Crossover Linux are both proprietary Wine based programs that was tweaked with various compatibility patches, more user friendly configuration tool, and support, to run Windows programs on both Mac and Linux.

To get the software, one must first register here, and here’s a note from the page: 

We are giving away all of our software for free on Tuesday, October 28th, 2008. This is a fully working, fully supported copy of either CrossOver Mac Professional, or CrossOver Linux Professional. No hooks, tricks, timebombs, or gimmicks: it’s the real deal.

 

To get your free software, simply enter your email below, confirm it, and enter the agreement code shown below. An email will be sent to your email address containing a serial code. Once you receive your serial code, go to http://register.codeweavers.com and register your software. Once you’ve done that, you will be able to log into your account on CodeWeavers’ web site, and download your product. PLEASE NOTE: your serial code must be registered on our site before 23:59 PM Central Standard Time. After midnight Tuesday, it is no longer valid.

 

(Please Note: if you are an existing CodeWeavers customer, this deal will give you a completely new support entitlement for another 12 months. That also means that if you’re an existing user of our Standard products, Merry Christmas: you’ve just been upgraded to Pro. For Free.)

*** Please note that the site is damn slow, probably due to overwhelming traffic of people trying to get the software, or it’s just Codeweaver’s tactic to minimize downloading by limiting their resources ***
