How to remove the existing NMS "instance" on Solaris, AIX, Suse Linux, CentOS, Ubuntu, RHEL RedHat Enterprise Linux, etc., due to error on installation;

"Error while checking for instances"

In some cases the above error will not be displayed but the install log (located at /tmp/ia/) will point to the default location when the current instance is at non default location.
Log sample:
 location: '/opt/nimsoft'

Delete the .com.zerog.registry.xml file, which should be located in /var or the user's /home directory.

You can also run the following command to locate the file:

find / -name .com.zerog.registry.xml

then remove it.

rm -f .com.zerog.registry.xml
