Ok, pues no se que decirte .. se supone que el ".txt" oficial o en su defecto:
http://www.php.net/manual/en/install.windows.php
Debería funcionar .. Por lo demas .. espera algun usuario de PWS .. yo uso Apache :)
Tambien es bueno leer los "user comments" del manual de PHP .. mira que dice este (ultimo):
Cita: Win98/PWS4/PHP4.2.3 (installer.exe)
Error Message:
--------------
The PHP4TS.DLL file is linked to missing export OLEaut32.DLL
More Details:
------------
Using Win98 (no Service Pack or SP1) and getting the above error (or something similiar to do with COM commumications or OLE) when you type "php -i" from the command line.
Solution:
--------
Upgrade to the latest and greatest DCOM download for Win98 (which is version 1.3 at the date of this submission) and all your problems should be solved
Un saludo,
