When you attempt to install Microsoft Speech Server 2004 on an x64 edition of Windows XP or Windows Server 2003, Setup verifies that your computer meets all the prerequisites. During the install, Setup reports that it cannot locate IIS.

This problem occurs because the Speech Server 2004 Setup program expect to locate Inetinfo.exe at %SystemRoot%\sysWOW64\inetsrv, but IIS 6.0 installs it at %SystemRoot%\System32\inetsrv.

To workaround this problem, copy the Inetinfo.exe file from %SystemRoot%\System32\inetsrv to %SystemRoot%\sysWOW64\inetsrv.
