That is line 158 of INSTALL doc in the php-5.0.0RC2-Win32.zip

I'm not an official bugs administrator but I might know the answer. 

I think they moved the files in the dlls directory into the main directory. (Where php.exe is) As far as I know, with PHP5, you don't need to copy/move any files to your windows and system32 directories anymore. Just extract the zipfile into a directory. Edit php.ini. Create the mappings in IIS. (.php > C:\your-installation-dir\php.exe). Restart IIS. And it should work.

Also, make sure that you remove any php files from your windows and system32 directory from previous PHP installations.

That's correct; we moved them to avoid the need to put anything outside of you PHP install dir, as that causes people many problems when they upgrade (they always forget to check their system dir).

Making this a documentation problem.

I don't have karma to update the INSTALL file, but I'll make a patch for it and I'll update this in the migration appendix.

I found another on line 181 of INSTALL.

"Since PHP 4.0.5 MySQL, ODBC, FTP...and XML support is built-in."

This is not true.  I was told by a friend, "MySQL is not loaded because of licensing problems"

Will you be patching the whole chapter "Installation of Windows extensions" on the INSTALL?

There is no dlls/ directory - the dlls in the root directory of php work, but without copying them to system32 during an upgrade, many problems arise.

Bring back the dll directory so we can see which ones need to be put into system32

ok it might all run from the one directory but as a sysadmin running it form that one directory involves changes to enviromental variables etc to get php5 working properly

and please update your documentation to reflect any changes!!! the installation docs are far from easy to read

None of them need to be put to system32 (according to our very latest install instructions, which are in effect in the manual sources since yestarday). Watch out for new manual builds coming out in the comings days or next week, or a bit later containing the completely rewritten windows instructions with more tips, information and an easier install method.

The INSTALL file in the windows distribution probably still needs to be changed.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
