Hi ,

Do you have compatible JRE on you machine?

Re: Can't open workbench

It's a question of JRE version.
Try to uninstall it from your PC and to download another version (up-to-date).

Re: Can't open workbench

Do you have a directive like the following in server.conf? If so, be sure it references the correct Java version. If not, you could try adding one.

com.kintana.core.server.WORKBENCH_PLUGIN_VERSION=1.5.0_15
