When trying to log into the plugin registration tool I get the error.
The server was unable to process the request due to an internal error

I have added the information to WEB.CONFIG
<serviceBehaviors>
<behavior name="debug">
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>

<services>
<service name="XRMServices" behaviorConfiguration="debug" />
</services>

I still cannot see detailed errors. This happened after installing 9.2. I am using the latest SDK Plug In tool.

How can I find out what the internal error is or is there a known fix for 9

This release has caused me no end of grief.
