Error calling GetFilterVersion on Apache to Tomcat Redirector ISAPI Filter - 32bit W2K8 SP2 Standard
There could be multiple reasons for this. Some most common being:
- Some dependencies are not being resolved for the 32-bit DLL. Open this DLL with Dependency walker and check for any errors in it (Skip the warnings in it). In most cases all dependent libraries are present, in such cases LoadLibraryEx error may come up because of the VC redistributables of specific version not present (If the DLL was built from VS 2010, the VC 2010 redistributables are needed).
- Read permission for this DLL is not available to the application pool in which your website is running. Check properties of your website to see the user and make sure this user has permissions to the DLL.
