Will HTML Validator run on Windows 3.x, a Mac, or Unix/Linux?
CSE HTML Validator v8.0 and above require Windows 2000, XP, Vista or above. Windows 9x is no longer supported due to OS limitations. CSE HTML Validator v7.0 and below are designed to run on the 32-bit power of Windows 98, Me, 2000, XP, Vista and above. It may work with Windows 95, NT 3.51, and NT 4.0, but is not tested on these older platforms. Due to resource and technical requirement issues, we are not currently working to support any other platform. So no, it will not work with Windows 3.x, a Mac, or with Unix/Linux unless you have an emulator or virtual PC program and can run Windows 32-bit applications.
