Error Message When Uninstalling Java web start application in Program and Features

Hi. I'm having an issue when uninstalling our application in Program and Features. It says "An error occurred when uninstalling <application name>. It may have already been uninstalled."

Ever since we used the "install" attribute in our jnlp file for the application to appear as installed in the Program and Features, this happened.

I found a similar issue regarding uninstalling applications in windows: http://bugs.java.com/bugdatabase/view_bug.do?bug_id=7053087

but it didn't say what was the specific issue. Also our jnlp file has the codebase and href attribute.

OS: Win 7
Java installed: Java 8u45

Does anyone know what causes this error message, or this is related at all with the "install" attribute?

Thank you very much.
