What version of Eclipse are you installing into?
The installer does not appear to be identifying the Eclipse version correctly.
Try running the installer with the -out
options to generate a log file. For example:
GWTDesigner_v5.1.0_linux_x86.bin -out installer.log --verbose
This will run the installer in verbose mode and redirect output to the file installer.log
in the directory where the installer is located. Examine the log file to determine the cause or send the log file to support and we'll take a look.
