You probably didn't copy the .dll's from the dll folder to somewhere in your path. It works fine for me, not a bug -> bogus.

Derick

I've made sure all the dlls were installed in the prescribed places (in my case, php_mcrypt.dll in c:\php\extensions, and libmcrypt.dll in winnt/system32), updated php.ini to point at the correct extensions directory, and I get this message:

PHP Warning: Unable to load dynamic library 'c:/php/extensions/php_mcrypt.dll'

Yet that file is confirmed as existing. Even if I have made some error elsewhere in the setup, that warning message is either wrong or insufficient.

How does the line in php.ini look like, and are you sure all .dlls have permissions to being executed/read by the Webserver User? (No idea how exactly this works in Windows)

; Directory in which the loadable extensions (modules) reside.
extension_dir = C:/PHP/extensions

extension=php_mcrypt.dll

(all other extensions are commented out)

I explicitly set the permissions for 'everyone' to 'full control' on the dlls. Still no luck.

You probably missed the bit in the manual (http://www.php.net/manual/en/ref.mcrypt.php) about downloading binary version of mcrypt library from http://ftp.proventum.net/pub/php/win32/misc/mcrypt/

the whole directory including the extensions got read and  execute permission for the IUSR-Account. This Account is the Account twhat the Webserver is using

No, but you probably missed the bit in my comment above that reads, "I've made sure all the dlls were installed in the prescribed places (in my case, php_mcrypt.dll in c:\php\extensions, and libmcrypt.dll in winnt/system32)".

I just re-tested using latest stable cvs snapshot from cvs.php.net and all 3 tested web servers (Apache, Apache2 and IIS) have no problems loading php with mcrypt so it must be some local configuration issue on your end.

i tried both msql (mysql.dll and mssql.dll) dlls and i also tried the pdf dll - without success

Got a pretty similar problem witj loading some extensions on win XP...

Some works (cpdf.dll, gd.dll for instance) but some others refuse to load. Quite usefull extensions like sablotron or xslt or domxml... every time i get the "cannot load module/procedure not found or module not found" message... I got it bad... I am going really mad at this... I need to run xsl transformation... Is there any other way to do it... I mean whitout xslt.dll or sablotron???

Thanks...

I was also getting the error message 

"Unknown(); Unable to load the dynamic library "C:\PHP\extensions\php_pdf.dll" - the module wasn't
found"

on winXP. I ended up copying all the .dll's from both the extensions and dlls sub-dirs to my c:\windows\system32 subdirectory and it works fine now for me. A very frustrating problem. It must be something with the XP environment path space as I did not have to do this on my windows 2k box or 98 box.
