Affinity, which makes graphic design software for the Mac, has launched its previously-announced free Windows beta for Affinity Designer.

In a blog post, the company states that Windows PC users will have to have the 64-bit version of the OS to run the beta. It adds:

It's important to remember the Windows beta version is far from the finished article and at this stage it might not work perfectly. So at the same time, we'll send you more information about how you can help us fine-tune the program further during the beta period – a crucial part of the process. Of course we understand that being part of a beta trial isn't for everyone, and some people would rather wait for the finished product to go on sale. But we really hope that you'll choose to sign up to be part of the trial.
