Most people don't want to even worry about server/system requirements, because it can be complicated stuff. There are however a few things you need to be aware of in order to install Responsive Layout Maker:
Operating System
To install the software, you must have Windows Vista, Windows 7, Windows 8/8.1 or OS X 10.7+
Browsers
You also need to be using a modern browser. We support IE9+, Chrome, Firefox, Safari and Opera.
What about Windows XP?
Officially we no longer provide any support for Windows XP as this operating system is scheduled to be discontinued by Microsoft on April 8th. Our software however should still run without any issues, but should some arise, we may not be able to help you out. We understand that many people may disagree with Microsoft's decision on this, but we simply cannot invest time/resources into an operating system that Microsoft has discontinued.
