Re: Unable to launch Workbench using "Open Workbench on Desktop"
To make a couple of initial checks,
Do you have the admin access on the machine you are trying to open the workbench? If not, then ask your network admin to either give you temporary admin access on your machine or ask the network admin to login to your machine and then login to PPM and use option 'Open Workbench on Desktop'. This will install several Jar files on your local machine and other supporting files that will allow to open Workbench directly without logging into the html interface.
This option downloads a different set of files into a different directory area, than when you choose the option 'Open Workbench', that simply refers to the JRE on your local machine. For the 'Open Workbench on Desktop' option, it installs from the PPM server itself various jar files including the knta_client.jar, etc. that it needs to run Workbench without the html interface.
