Thanks for your response.  I don't believe the problem is realted to
Vista security.  I have full administrator rights.  I also turned off
the "User Account Control" (that nuisance which pops up whenever you do
anything, to ask if you really want to do it.)
The error happens in ntdll.dll, which is what Windows uses to load DLLs
in general.  It's happening when PHP-Mapscript is loading its dlls.
Just as an experiment, I removed all the dlls, and started adding them
one-by-one, to see which one might be causing the error.  It happened
when I added libxml2.dll.  Since I am calling PHP from a C++ program, I
was able to suppress the general protection fault error, and then
Mapscript loaded and ran OK.  I guess I am not currently using any
functions from the offending dll.  So, it is sort of working, but there
is some underlying problem that is bound to come up again for someone.

Yes I have run MS4W on Vista.  It seems the added security in Vista does

cause some problems, which could be related to your issues.  The MS4W
README has a few notes on Vista (for installing the Apache service):


Could it also be a permissions issue for your problems?
