I even run the command prompt as Administrator but it didn t work for me with the below error    keytool  is not recognized as an internal or external command   operable program or batch file    If the path to the keytool is not in your System paths then you will need to use the full path to use the keytool  which is   C  Program Files Java jre lt version gt  bin   So  the command should be like   C  Program Files Java jre lt version gt  bin keytool exe  -importcert -alias certificateFileAlias -file CertificateFileName cer -keystore cacerts   that worked for me

This could happen if you are not running the command prompt in administrator mode   If you are using windows 7  you can go to run  type cmd and hit Ctrl Shift enter  This will open the command prompt in administrator mode  If not  you can also go to start -  all programs -  accessories -  right click command prompt and click  run as administrator

For Mac users make sure to sudo and when prompted first give your administrator password and that will be followed by keystore password which typically should be  changeit  unless you actually changed it
