When trying to install Spectrum on Redhat Linux the following error is encountered ....
Graphical installers are not supported by the VM. The console mode will be used instead...
Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)
Release: Any version installed on Linux up to 10.4.2.2 included.
Missing the libXtst RedHat Package Manager (RPM) which is required for a GUI install.
Install the libXtst RPM and its dependencies.
NOTE: Both the 32 bit and 64 bit libXtst RPM and its dependencies are required.
An alternative would be to do a Spectrum distributed install, which excludes the GUI's from the install process.
Please reference the "System Requirements for Linux" section of the documentation for more information.
