I just downloaded and installed igination 7.2.5. Then I downloaded the MES module “OEEDT-Installer-module.modl.zip”. That has a .jar program that runs with an error “Failed to load Main-Class manifest attribute from C:…\oeedtinstaller.jar”

Then I downloaded the MES manual, and it says to install it from within ignition using the .modl file, but I can not find a .modl file to download. Please help.

Thanks,
