We have had a number of reports from different labs seeing this error at startup:

java.lang.ClassNotFoundException: com.softworks.roes.app.ROESApp

                at java.net.URLClassLoader$1.run(Unknown Source)

                at java.security.AccessController.doPrivileged(Native Method)

                at java.net.URLClassLoader.findClass(Unknown Source)

                at com.sun.jnlp.JNLPClassLoader.findClass(Unknown Source)

                at com.sun.javaws.Launcher.run(Unknown Source)

                at java.lang.Thread.run(Unknown Source)

 
In each case clearing the Temporary Internet Files from Java Control Panel worked, as follows:
 
Open Windows Control Panel, then double-click Java in the list to get the Java Control Panel
Click Settings... in Temporary Internet Files at the bottom of the General tab
Click Delete Files...
Click OK at the prompt to remove all applets and applications, etc.
Click OK to exit out of Java Control Panel
 
Start ROES from the lab web site link
