Exception thrown in FP Library: Error -10153 Unable to load PAI Module

I have now moved a little closer to solving my problems.

I am now getting the following error in my log files.

"Exception thrown in FP Library: Error -10153 Unable to load PAI Module"

I am trying to run an application on a 64 bit Windows 2008 R2 machine.

The pai_module.dll I am using is version 3.2.98 I have previously used version 3.1.70.0.

The dll is located here 'C:WINDOWS\System32' on both machines

I do not get the error on my local machine where I am running it on Visual Studio 2010 app server.

The error is shown when I run it on IIS 7 on a 64 bit Windows 2008 R2 machine.

The question is - Am I running the correct dll?

Is it located in the correct place?

If not what is the correct version to use and where is the correct place to place it?

Regards

Phil
