Re: [Mod-security-developers] WS2008 R2 SP1 (64bit) IIS 7.5

[Jan v. V. <jan...@it...>]

Greg,

Did the same tests with the new 2.7.1 but no progress.

In the event log I only have:

The Module DLL 'C:\Windows\system32\inetsrv\modsecurityiis.dll' could not be loaded due to a configuration problem. The current configuration only supports loading images built for a x86 processor architecture. The data field contains the error number.

I have modsecurity enabled in the web.config  (without, the error is also present - when I add <remove name="ModSecurityIIS" /> no error)
The webconfig is set to: <ModSecurity enabled="true" configFile="c:\websites\wesbitename\modsecurity.conf" />

The conf file is at the same level as the web.config.
As the error points to a 'configuration problem' I fear my conf is wrong. I worked through the wiki and google but cannot find any pointers to how this conf should be configured for windows and where the actual activated_rules should be.

modsecurity.conf (comments removed):
