This page contains information and answers to frequently asked questions about CrossOver and Licensing.
Tangible things you will get now:
You'll be able to start those Windows applications from your dock or whatever menu you like best. Applications, notably games, will run at essentially the same speed as they do on Windows. And all of this without having to buy or run a copy of Windows itself.
Paying customers can submit problems to our elite Ninja support team. As of September 2015, their average response time was 2.5 hours per email. Obviously, some responses are a great deal faster, and some slower. But the bottom line is that we respond to all of our customers as quickly as we can. So if you don't hear back quickly, check your spam folder. You can refer to our support page for details on all of our support options.
The catch is that CrossOver doesn't run every Windows program, and some programs that do run, run with flaws. We have excellent resources to help you see whether or not your application works in our Compatibility Center, and a lot of other tips and support options in our support center.
Tangible things you will get in the future:
During your one year support period, you will be able to download all versions released and you will be able to obtain technical support. Upon the expiration of that time period, all customers will still be able to download the most current version of the software that they received while under the support agreement, forever (or at least as long as we can practically make that possible). See our Upgrade Policy for more information on how to upgrade.
We're committed to providing community resources so that our customers can help each other. The Compatibility Center is key to that - with tips and tricks, discussion forums, and much more. We also continue to host the Wine website so that you can always turn to the broader Wine community.
We also provide forums to foster direct communication between our customers and so that you can exchange tips and learn from the experience of each other.
Intangible benefits you will get:
You will be helping to provide a much needed source of income to a Free Software company that has provided a large range of valuable improvements to one of the most key Free Software Projects - Wine. You can see a list of what we have done on our Support Wine page.
CodeWeavers will use the revenue from the end user version of CrossOver to continue its work on Wine as well as to enhance and improve our products.
The interaction of CodeWeavers' CrossOver products with those of Microsoft raises legal issues around what Windows software can be run under Wine. In order to help our customers better understand these issues, CodeWeavers has compiled a list of commonly asked questions and their answers.
Q. Can Microsoft sue CodeWeavers or its customers for copyright infringement or reverse engineering, either for Windows or its Windows applications such as Microsoft Office?
A. No. The underlying technology utilized by CodeWeavers to enable Windows software to run under Linux is an open-source technology called Wine. Wine has been developed completely independently, with no reverse engineering and no access to Microsoft source code. The Wine source tree, with a complete revision history since the inception of the project, is freely available to the public, and demonstrates that Wine is strictly separate from Microsoft's proprietary code base.
Q. Can Microsoft prevent CodeWeavers' customers from running Microsoft applications on Linux?
A. No. Microsoft's end-user licenses do not preclude operating their applications under other operating systems. Were Microsoft to attempt to prohibit such usage, by requiring that Microsoft products be run only on the Windows OS, they would be in violation of the Sherman Anti-Trust Act. The Sherman Act precludes making the usage of a non-monopoly product dependent on the purchase of a monopoly product. Microsoft has been convicted of monopolistic practices under the Sherman Act regarding their operating systems. As a result, they cannot legally make the Windows OS a prerequisite for running a Windows software application.
Q. Isn't Wine a risky new technology?
A. No. In fact, Wine has been in active use since 1993. Since then, it has been adopted by many large companies and integrated into their products, including Borland®, Google®, IBM® and Sun Microsystems® (now Oracle®). Wine is a stable, well-understood technology that is being continuously refined and enhanced.
Q. Can Microsoft change its Win32 application programming interface (API) and break Wine?
A. Sure, if they also wanted to break every other application on the planet. There is a common misperception that Microsoft changes the Win32 API on a constant basis, making it difficult for Wine to "keep up". This isn't true at all, since changing the API would break Microsoft's existing codebase, as well as those of many other software developers. So long as other software vendors produce or support programs for multiple versions of Windows, Wine will work too.
