This software supports Windows (2000/XP/Vista) in both 32-bit and 64-bit versions. Version 1.62 is the last version of Wilbur reported to work with Windows 98 – the current version does not. You will need a working OpenGL version 1.4 or later implementation, even if you do not use the 3D preview feature. A multi-core processor is recommended starting with version 1.63.
