Error: TibrvException error=22 message=Version mismatch: tibrvj shared library version 8.2 does not match version of .JAR file 8.1

Error:TibrvExceptionerror=22message=Version mismatch: tibrvj shared library version 8.2 does not match version of .JAR file 8.1

When you Install Tibco Runtime Agent 5.6.2, it updates your Rendezvous Jar files to 8.2 . Problem is that Hawk is not compatible yet with Rendezvous 8.2, so when you try to start Hawk Display 4.8.1 in Windows after installing Tibco Run-time Agent 5.6.2 you will get this error

To fix this problem

Go into

Control Panel -> System and Security -> System -> Advanced system settings -> Environment Variables

Edit  tibrv definitions in CLASSPATH and PATH, put the 8.1 first, then 8.2

Now Launch Hawk Display
