Truth in Advertising: The Real Dirt
Tangible things you will get now:
- The ability to easily install and run many Windows applications.
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.
- Kick-ass support
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.
- Not everything works.
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
and a lot of other tips and support options in our
Tangible things you will get in the future:
- Support and upgrades
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.
- Community resources
We're committed to providing community resources so that
our customers can help each other. The
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
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.
CrossOver and Microsoft
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.
Can Microsoft sue CodeWeavers or its customers for copyright infringement or
reverse engineering, either for Windows or its Windows applications such as Microsoft
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.
Can Microsoft prevent CodeWeavers' customers from running Microsoft applications
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.
Isn't Wine a risky new technology?
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.
Can Microsoft change its Win32 application programming interface (API) and break Wine?
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.
