Windows XP Upgrade Advisor Warning About the IrDA Protocol (Q308368)
When you upgrade from Windows Millennium Edition (Me) to Windows XP Home Edition or Windows XP Professional, Upgrade Advisor may display a warning message about the Infrared Data Association (IrDA) Infrared Communications protocol:
This version of IrDA Protocol will not work with Windows XP
This warning appears only on computers that have an installed infrared port. Laptop computers often have an infrared port.
In most cases, it is safe to ignore this warning. The Windows Me IrDA protocol stack is removed by Windows XP during the upgrade process; the IrDA protocol stack is replaced with a new version of the IrDA protocol stack automatically. There is no need to download or install any additional software or patches.
Some older, third-party, IrCOMM-protocol programs that were written for Windows 95, Windows 98, or Windows Me may not run correctly on Windows XP. If this issue occurs, it does not prevent Windows XP from running properly, but the IrCOMM program will not work until you obtain a version of the program that is compatible with Windows XP.
