Mercedes EPC.net EWA failed to validate certificate solution
When i install Mercedes Benz MB Star diagnostic EPC software program,i got the EWA Client Tools error “EPC failed to validate certificate. The application will not be executed”
Solution from mbstartool:
Don’t try to update your java. Uninstall java completely, reboot and install java from the EWA server download page
It’s a certificate issue.
Uninstall all Java versions and reinstall Java SE8 update 40 from the “download” section of EPC.net. See pic below.
