We want to create and install a custom provider plugin to add our own logic to the security when queries are run.
We are able to compile the .net code using the SlxPluginBuilder.exe to make the wrapper file (.tlb)
Original we were able to use the SlxProviderPlugin.exe to install the custom provider in version 7.5.0
Now we are trying with 7.5.4 and the SlxProviderPlugin.exe keeps crashing.

Here are instructions on how to create the provider plugin for custom security.

Also the SalesLogix LAN Developers documentation has an entire section on this

Any ideas on how to accomplish would be appreciated.

Thanks
