Hello Ajay,
When you say "Then using command prompt I ran the IdentityAccessManager.exe; I could see no messages on the command prompt". Are you not seeing messages at all in the command prompt?
You should be able to see something like:
Calling "C:\PROGRA~1\CA\DEVTES~1.366\IDENTI~1\bin\standalone.conf.bat"
JAVA_HOME is not set. Unexpected results may occur.
Set JAVA_HOME to the directory of your local JDK to avoid this message.

JBoss Bootstrap Environment
JBOSS_HOME: "C:\PROGRA~1\CA\DEVTES~1.366\IDENTI~1"
JAVA: "java"
JAVA_OPTS: "-Dprogram.name=standalone.bat -Djboss.http.port=51112 -Djboss.https.port=51111 -Djboss.bind.address.management=0.0.0.0 -Djboss.bind.address=0.0.0.0 -Diam.truststore=../iam-truststore.ks -Diam.truststore.pass=passphrase -Dkeycloak.migration.action=import -Dkeycloak.migration.provider=iam-updater -Dkeycloak.migration.dir=../realms-to-import -Dkeycloak.migration.strategy=IGNORE_EXISTING -Diam.version=1.2.0"

Please, take a look at the links below. It is some issues faced when starting IAM for the first time. However, the messages in the command prompt would give us a hint of what may be happening:
IdentityAccessManager -Protocol family unavailable - CA Knowledge
Unable to start Identity Access Manager service in - CA Knowledge
DevTest10.4 IAM error - Address already in use: bi - CA Knowledge
Hope it helps.
If you are still having issues to start IAM, please open a support ticket so we can take a look at it.
Thank you,
Heloisa
