Zend Server 5.6 - Failed to load extension 'codetracing'

[fixversand]

Today i updated our Zend Server to 5.6 SP1 and added the Hotfix 4.
Right after the update the Zend Code Tracing doesn't want to load properly. (it worked before)
I just get:
Error message: Failed to load extension 'codetracing', path given: 'C:\Zend\ZendServer\lib\codetracing\php-5.2.x\ZendCodeTracing.dll'
The file is at the right position and has the following details:
Fileversion: 0.0.677.0
Size: 438 KB
Last Modified: 02.29.2012 14:38

The Server-System is: Windows Server 2008 R2 SP1 x64

I tried to turn it off, restart PHP, turn it back on. => Nothing changed (as expected)
Changed the path of the file to see if ZS is tring to get the right file. => It's the right one.
I modified the tracing configuration a little (and back) to ensure the config file is okay.

Any more ideas what might be done to get it working again?
(The de- and reinstallation should be the far latest option :-) )

The problem still persists. :-(

Maybe the dll is damaged?
Since the setup does not offer a "repair" option i tried to extract the dll from the setup but i failed. 7-Zip is not able to handle the second compression. Doh!
Will now try to install on a other system and copy the dll.

Any other ideas?

Switching the DLL didn't fix the problem. But in a fresh installation (VM) the codetracing is working. At least i know the dll is okay. ;-)

I compared zend.conf, httpd.conf and php.ini with a fresh installation.

There is one difference in the http.conf:
<Directory "<path-to-zend>\Apache2/htdocs">
AllowOverride All
By default it's set to None.
Changing this didn't solve the problem.

In the php.ini is one difference:
include_path=".;<path-to-zend>\ZendServer\bin\pear;<path-to-zend>\ZendServer\share\ZendFramework\library"
Removing this didn't solve the problem.

Combinations of both didn't solve the problem either.

Seams i have to reinstall the server to fix ths problem. But with this i maybe generate new problems ... :-/

It could be some leftovers from an older version. If other Zend extensions loaded fine then its probably not a permissions issue with the extension directories. If it happens again we can have a look at it. In many cases there would be some error in one of the logs.

Problem still exists. :-(

After comparing every file with a fresh installation on a -test- server i can say, there are just these differences:

• On the -buggy- server i installed into C:\Zend\
  On the -test- server i installed to the default folder. C:\Program Files x86\Zend\
• Some Events were changed. But using the defaults does not solve the problem.
• Some extensions were missing in the php.ini.
• some mime.types were missing the the Apache2\conf

That's it.

So i finally decided to deinstall Zend Server and reinstall it again to C:\Zend\. (Folders were empty except MySQL Databases and htdocs)
But the problem still exists. DOH! :-(

Sorry, i was to slow to be able to edit my prev post:

I just found some strange thing in the Zend Server\logs\zem.txt:

Code: Select all

Repeats a few more times.

The strange thing is: The Server does not have a Drive F: ?!? And there is no Drive E: , too. So its not the "Next free one" for some sort of temporary mappings.
And in the given path, there is a doubleslash behind "codetracing". Should not be a problem, but maybe it is?
'C:\Zend\ZendServer\lib\codetracing\\php-5.2.x\ZendCodeTracing.dll'

FIXED!

I missed a error message in the Windows-Event-Viewer!

Verwenden Sie für eine detaillierte Diagnose das Programm "sxstrace.exe".

i wondered about the missing VC90. because it was installed! But the installed version is for x64! And it worked with the Zend Server 5.1.
With Zend Server 5.6 i had to install VC90 x86 and finally codetracing is working.
