Am i correct to assume that this IE9 does not work with windows xp pro and older version like 98?
Paulus Internet Explorer 9 Platform Preview will only run on Vista or Windows 7 according to Microsoft (and the linked server versions I assume). It is likely that this will also be true for the final release of IE9.
# What are the system requirements for Platform Preview?
# You need a Windows PC running either Windows 7 or Vista. On Vista, you need to have installed Internet Explorer 8 and you need to install the Platform Update for Windows Vista, available on Windows Update since October, 2009. Platform Preview is only available in a 32-bit x86 version but it will install and run on 64-bit Windows 7 and Vista
# Does Platform Preview run on Windows XP?
# No. Internet Explorer 9’s GPU-powered graphics take advantage of new technologies available in Windows 7 and back-ported only to Windows Vista. These technologies depend on advancements in the display driver model introduced first in Windows Vista.
