Cannot load mcrypt extension. Please check your PHP configuration. XP IIS

I used the 'Microsoft Web Platform Installer'

Its PHP Version 5.2.11 included in it, the previous standalone version I tried was also this version.

phpMyAdmin is version 3.2.2

My php.ini file is c:\Program Files\PHP\php.ini.

I use the link in the start menu to edit the file.

My PATH start with  c:\Program Files\PHP\;c:\Program Files\PHP\ext\;

Ok, so please check these things:

1./ in php.ini: extension_dir = "C:\Program Files\PHP\ext" exist?

2./ in C:\Program Files\PHP\ext, is php_mcrypt.dll exist?

3./ Did you restart your web server after you edit the php.ini?

To use mcrypt you need to install additional dlls on windows, which are not provided by the Windows installer of php
See http://www.php.net/manual/en/mcrypt.requirements.php

thetmanvn:

1. Yes
2. Yes
3. Yes. I used iisreset and I tried a reboot

hernst42: I have libmcrypt.dll

maybe you'll have less problems when using xampp. Just take a look at this.

I need to use IIS

Very strange here

Ok, try phpinfo() to check your output, to find more evidence, look out for mcrypt, my test result is below

Where did you place the libmcrypt.dll?
Did you use the correct version of libmcrypt?
Is the libmcrypr.dll readable by the IUSR_XXXXX?
You could monitor starting IIS with the FileMon and see which files are not loaded properly/are missing.

thetmanvn:

Mcrypt isn't showing at all in phpinfo

hernst42:

libmcrypt.dll is in C:\Program Files\PHP

>Is the libmcrypr.dll readable by the IUSR_XXXXX?
What ?

>You could monitor starting IIS with the FileMon and see which files are not loaded properly/are missing.
How do I do that ?

>libmcrypt.dll is in C:\Program Files\PHP

I thought that file must be in "C:\Program Files\PHP\ext" ???

>Is the libmcrypr.dll readable by the IUSR_XXXXX?

For the test, you should give read permission to user IUSR_XXXXX (XXXXX is your Server Name) to ext folder (or all php folder)

>You could monitor starting IIS with the FileMon and see which files are not loaded properly/are missing.
Use filemon from sysinternal suite http://technet.microsoft.com/en-us/sysinternals/default.aspx
(It's very powerful and easy-using suite for Windows Adminstrator)

>For the test, you should give read permission to user IUSR_XXXXX (XXXXX is your Server Name) to ext folder (or all php folder)

How do i do that, the IIUSR is only a member of guest.
I went into users within computer management.

I've downloaded sysinternal suite, but it doesn't tell you where to put the files in the zip file and filemon isn't in the zip.

>libmcrypt.dll is in C:\Program Files\PHP
should be in the system folder or any other folder that is available via $PATH

@hernst42: No, for using with php, libmcrypt.dll must in the folder that was specified in extension_dir in php.ini.

@mindwarpltd: Right-Click on C:\Program Files\PHP, choose Properties -> Security Tab -> Add User IISUSR_XXXXX, and give he a read permission in permission panel.

>Filemon and Regmon End of Life on 9/1/09 Process Monitor is the replacement for Filemon and Regmon and is much more advanced and scalable than its predecessors.

Sorry, I didn't update sysinternal suite info. From Sep, 1st, Process Monitor (procmon.exe) is replace for Filemon and Regmon. The suite is zip file, you can extract anywhere and use directly.

Ah, sorry,

libmcrypt.dll is in PHP Directory is correct. Noneed to be in System Folder, But php_mcrypt.dll must be in extension folder and must be enabled in php.ini (seem you've got it all).

>@mindwarpltd: Right-Click on C:\Program Files\PHP, choose Properties -> Security Tab -> Add User IISUSR_XXXXX, and give he a read permission in permission panel.

I don have a security tab, just sharing and web sharing, no where to add permissions.

So I just unzip the sysinternal zip and put them in a folder and put them on path ?

I've downloaded SCESP4I.EXE and that given me the security tab.

However, I don't seem to have an IIS user, I thought I had earlier, I have...

IUSR_AARONSERVER - Internet Guest Account

IWAM_AARONSERVER - Launch IIS Process Account

Is it one of those ?

>It seems you're using Windows XP???
Yes XP Pro

>Anyway, did phpinfo()  show you any extension was loaded?
Yes it showed loads of extensions, but not mcrypt

Ahh its

IUSR_AARONSERVER

I've added Read & Execute, List Folder Contents and Read permission to the PHP folder.

I've used iisreset and phpinfo and still no mcrypt :(

Use must use IIS, ok?

But before this can you test whether your application works normally with other bundle?

I prefer to xamplite, you can download here:

http://www.apachefriends.org/en/xampp-windows.html#646

Stop your IIS, and mysql if you have yours, or you can change Apache2 for preventing port conflicting. Just for test before go further, because, your config and installation seems correct.

Or you have another machines for testing, start from scratch, too see whether it works or not. I must go now, discuss with you later.

I was thinking, this has to be something with the mcrypt files I'm using.
Sure enough, although the files were the right version, the time was different 19:41 whereas all the others were 19:36.

So I ran the standalone install and its now working.
I did try this before, so I guess something we've been doing has help.
