A. C4 does different things for different audiences. The Compatibility Center contains the following components:

• A database of Windows applications, including information and statistics about how they run under CrossOver.
• An online discussion forum and community surrounding each of those applications, where people can discuss the application and any known issues.
• A front-end for the CodeWeavers regression testing suite (CXTest), allowing us to automatically collate information on the state of CrossOver's functionality vis-a-vis a very large number of Windows applications.
• A locus for interested parties (advocates, ISVs, etc.) to get applications running under CrossOver

A. C4 is different in a number of different respects:

• It is actively maintained.
• It is more comprehensive.
• It allows financial incentives to be aligned behind which applications will be supported under CrossOver, thereby giving us an active interest in bringing new applications into support
• It allows for the dissemination of a uniform toolset that can be used by anyone to test their applications against CrossOver.

A. They indicate different levels of functionality under CrossOver. Go here for more information.

A. Probably because no one has submitted it to the database yet. If you're interested in submitting an application, click here to be taken to the correct spot to do that.

A. Not necessarily. Many applications work perfectly under CrossOver without any modification whatsoever. However, we may simply not be aware of them. So, just because an application isn't in our database doesn't mean that your application won't run. You might consider downloading the trial version of CrossOver to see if your application works. And if it does, please consider submitting it so that it makes it into the database.

A. Download the trial version and find out. That is by far the fastest, easiest way to answer this question. Regardless of whether the answer is "yes" or "no", we'd love it if you would submit the application to the database.

A. Absolutely. Depending on your situation, there are a number of things you can do. These include:

• Becoming an advocate for the application in question. Volunteering your time can help us accumulate better data on the application in question. And as CrossOver Wine continues to improve, odds are the application you need will improve under CrossOver as well.
• Pledging some level of monetary support to bring the application in question under support. If we reach an economically meaningful amount of money on the table, we'll bring the application up under CrossOver. You'd be amazed how quickly a group of individuals can accumulate the necessary funds. Of course, if you have enough money by yourself, so much the better. <grin>
• Contact the software developer, and suggest that they work with us to make their application function under CrossOver.

A. Answer: it really all depends. Supporting a big, important application that we think we can potentially drive more sales of CrossOver can be a factor to bring the cost down. This is particularly true if we know beforehand that {Customer X} will buy {Z Thousand} seats of CrossOver if the application in question is supported. On the other hand, if the application is known to be big, gnarly, and complex, that brings the cost up. As a result, we review our supported application roadmap on a case-by-case basis.

A. That's a lot like asking, "How much does a house cost?" Again, it really all depends. How complex is the application? And what qualifies as "runs well" for your production environment? The answers to both of these questions can have a dramatic impact on the likely cost of an engagement. For more information on how we approach CrossOver implementation projects, go here.

A. Absolutely! We have a set of services designed to help ISVs get their products running on either Mac OS X or Linux under CrossOver.

A. Sadly, no. We've learned through experience that there are no "Killer Applications" out there whose support will help us sell a buhzillion extra units of CrossOver. We really wish there were, but so far it's never happened. That's not to say we won't give discounts on development work if we have a large sales opportunity sitting in front of us. But in general, we are a "coin-operated" company: if you need an application to work, you'll need to cover our development costs and profit margin.

A. Our experience suggests that the answer to this is most likely "probably not". For all practical purposes, we think we can make anything run under CrossOver. After all, if we can make MS Office run, odds are pretty good that we can get your application running, too. The only question is how much work is entailed.

A. Advocates are the dedicated, talented, and extremely sexy people who help us maintain the Compatibility Center. Advocates dispense their wisdom concerning their favorite Windows applications to other users, as well as helping us test applications. If you think you might be interested in being an advocate, here's some more information on what they do, and the perks they get as a result.

A. Yes. There are two ways to do this. First, if you want email updates for all applications, go to your Account Subscriptions tab and check the C4 Apps checkbox. Then click Save Account Changes.
If you only want updates for a single application, you can add it to your favorites by clicking on the 'Add to Favorites' link on the bottom of the application details page. Once added, go to your My Favorites page and check the checkbox in the subscribe column. Then click the 'Update Favorite Applications' link.
