I want detailed explanation to...

Hi everyone:

I have the Error: FAILURE :E-mail settings saved successfully. Could not find valid certification path to requested target, so kindly configure to apply Trusted/Self Signed Certificate.

So, I ruined the process (I think) about http://kbase.zohocorp.com/kbase/ServiceDeskPlus/TroubleShooting/file_100004.html

And then...

C:\ManageEngine\ServiceDesk>gencert.bat MYSERVER 995

C:\ManageEngine\ServiceDesk>jre\bin\java -cp lib\cert.jar InstallCert MYSERVER

I don't understand what is the steps exactly. Could you explain detailed?

Thanks.
