I had 1.4 running fine. Downloaded 1.7c got through the install and the Java runtime. Get the following msg when trying to launch.
"error: java.lang.reflect.invocation Target Exception"

I'm running W2K. Have downloaded and reinstalled serveral times. Have tried to uninstall 1.7c several times, the Uninstall shield goes though it step by step but doesn't erase any files.
