[mapserver-users] ms4w v5 broken on install -- php-cgi cannot find xerces entry point

[Jeff McKenna]

Interesting.  Odd that no one else has been hitting this issue.  So  
this is a fresh machine?  Is it possible that another 'xerces- 
c_2_7.dll' is being found in your environment?  Yes it does smell like  
some version of "dll-hell".  Myself I often have  a million different  
foss4g tools installed and I sometimes hit that dll conflict wall.

What is your exact environment?  Maybe it's a Vista-specific issue  
with MS4W?
