Hi!

Thank you, this post has helped me solve the problem.

My specific problem was with PostgreSQL and a message like ‘Could not find driver’.

Hi,

can I cry yet? I have installed WampServer 2.2, which bundles PHP 5.3.8, on my work computer (XP Pro, v2002, SP3). It’s installed just fine, but I, too, have received the mysterious error. After much googling & copying of dll’s all over the computer, I’m still not having any luck. Here are where the files are:

ntwdblib.dll
/ext
ntwdblib.dll
php_mssql.dll

/system32
ntwdblib.dll
php_mssql.dll
msvcr71.dll

as you can see, I’ve copied just about every dll I can find to every folder mentioned on this page (ok, that’s a bit of an exaggeration), but at least the required files are in the required folders. but I still get the error message 4x, since I have both php_mssql & php_pdo_mssql enabled.

are there any other suggestions someone might make that could help? I’ve had previous version of wampserver & php work on the machine, but no luck with current versions.

I tried copying the libpq.dll that was in the ext folder under php to apache\bin and leaving the ssleay32.dll file alone. That appeared to fix the issue. Thanks so much for your guidance!

Hi,
This information is very helpful! I tried copying the ssleay32.dll file from my php directory to the apache\bin directory. There was already a ssleap32.dll file in apache\bin, so I renamed it. After I did this apache would not start. We are trying to get pgsql working in a test installation of XAMPP.

You cannot run php_mssql.dll just like that, it’s not an executable like an *.exe file. This post is about having problems with loading the dlls. What are you trying to achieve?

I couldn’t load the mssql extension for months. I searched the ntwdblib.dll & I copied to the %windows/system% directory and worked!
Thanks to the author.

Thank You, Stanislav Stoqnov. You have solved my problem. I was just about to scrap my project and start over.

The msvcr71.dll was present in the MS SQL program files directory, but not in the system32 folder.

Thank you very much Abel for posting the detailed and step-by-step guide. I found that the search order was most interesting. Although not listed, your post helped me figure out the problem I was experiencing.

The system I was troubleshooting was Win 2008 R2 ENT, using IIS7.5 with PHP 5.2.17. I installed PHP using the web installer tool that comes with IIS7. (So much for an easy install…) The problem I had was a PHP startup error on php_mssql.dll unable to load. There were others but this was the one I needed. Obviously the php_mssql.dll was present in the ext folder as well as the ntwdblib.dll in the PHP root folder.
My solution ended up being the “msvcr71.dll” as “Stanislav Stoqnov” in the comments here pointed out. Adding this file to the C:\Windows\SysWOW64 directory solved the issue for me.

Thanks again!
