"Failed to initialize the managed interoperability layer of Microsoft Dynamics AX."

Hello,

My .NET application utilizes the .NET Business Connector to interface with Dynamics AX.

I'm receiving the following error on the LogonAs function:

"Failed to initialize the managed interoperability layer of Microsoft Dynamics AX."

I was able to get the .NET Business Connector to work previously on a different deployment and I never got this error. I'm not really sure how to debug this one.

Any ideas?
