Hello Eduardo,
Thank you for your message.
Unfortunately, we don’t offer private alpha-testing. However, as soon as a beta version is available for testing, we usually offer it for open public beta testing on our website which is available to all our users. For example, currently we have a beta version of Viewer for Mac/Linux and alpha version of Host for Linux available for preview/testing.
As for the Windows XP compatibility - all our modules are currently supported for Windows XP - you can find the exact system requirements for each module on our
Download page by selecting the
System requirements button.
Please let us know if you have more questions.
