ERROR: The Installation Manager cannot be started.The registry information does not exist or does not match with this executable.

Hello Everyone,

Hope you all are enjoying working with middleware and doing well. Today's issue is bit different. When I was trying to install fixpack on one of my environment of WAS 8.5.5.2 I was getting the below error. The error was actually it's not allowing me to start the IBM installation manager to install the fixpack. Means this error is not related to the fix pack installation. We are getting this issue because improper installation of IBM installationmanager. It will not allow you to even execute the command ./imcl. When I was trying to execute just ./imcl command, getting below error. 

Error:

.............................................................

The Installation Manager cannot be started. The registry information does not exist or does not match with this executable. This may happen if you are trying to run Installation Manager installed by another user.

ADMU0116I: Tool information is being logged in file

Cause:

In Error itself it's showing  that the Installation Manager cannot be started because you may trying to run Installation Manager installed by another user. We had installed the Webpshere environment using wsadmin user and then after according to the security standard of our organization we changed user to was. It was working fine for all application server/JVMs and it started all the JVMs. But when I try to start installation manager it's showing an error because when Installation manager was installed by user wsadmin it's registry file i.e. InstallationManager.dat got stored in /export/localhome/wsadmin/etc/.ibm/registry location, which is the user directory of previous user.

To resolve the issue I need to copy the registry file i.e. InstallationManager.dat to new user directory location i.e. /export/localhome/was/etc/.ibm/registry.

Procedure: 

Copy the registry file i.e. InstallationManager.dat from user directory of previous user to the user directory of new user

Hope this will help you. Kindly comment for your suggestion and quires.
