Error on NetTools Profibus Startup

I’m getting the error upon starting the NetTool software.

Error: 432 File name or class name not found during Automation operation.

My laptop is running windows 7 and the NetTool software version is, downloaded from the support site.

I get the same error when I installed the version provided in the CD that comes along with the
Anybus gateway.

Have you also downloaded the Transport Provider?

If you continue to get the error, please uninstall NetTool and the Anybus Transport Provider, then re-install both before you try to run the program.
