PMU Connection Tester Error

Aug 9, 2016 at 8:17 PM

PMU Connection Tester was installed correctly and worked well before. However, when I opened it today, there was a Microsoft .NET Framework error. The error is:

Unhandled exception has occurred in your application. If you click Continue, the aaplication will ignore this error and attempt to continue. If you click Quit, the application will close immediately.
Root element is missing.

After clicking Continue, PMU Connection Tester was open, but I could do anything on it and there was one sentence shown in Graph area. I reinstalled PMU Connection Tester and Microsoft .NET Framework for several times, but the error couldn't be solved. Did anyone meet this error before and give me some help?

Hi liyinbest990,

I believe the problem lies in Settings.xml, located in the "%appdata%\Grid Protection Alliance\PMUConnectionTester" directory. Somehow, that file has been wiped clean. Fortunately, all you should need to do to fix it is delete the file.

Also note that we've moved away from CodePlex and have retired these discussion boards.
