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<version>\bin

So, the command should be like

"C:\Program Files\Java\jre<version>\bin\keytool.exe" -importcert -alias certificateFileAlias -file CertificateFileName.cer -keystore cacerts

that worked for me.

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
