Solarwinds IP address trackern NOT opening run-time error 432

I have installed the newest version of Solarwinds IP address tracker on my windows 7 laptop. When I try to open it I get this message:

Run-time error '432':

File name or class name not found during Automation operation

I have uninstalled and installed it several times...run registry fixes....etc....

Can someone tell me what might be causing this issue.....?

thanks
