Update JRE caused viewON2 problems

From $1

Table of contents

 

After an upgrade of the Java Runtime Engine (JRE), it's possible that viewON2 will not start correctly.
It's due because, depending of the version, the new JAVA was installed in a different directory and then viewON2 cannot find its library.

To fix that:
- either you re-install viewON2
- either you copy the ViewOnExt.2.0.1.jar file (from the old Java directory) in the \lib\ext\ directory of the new Java installation

Usually, the file path is:
C:\Program Files\Java\jre6\lib\ext\ViewOnExt.2.0.1.jar

REM: Some users have also required a Windows Restart to solve the problem.
