How to remove the existing UIM "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 actually at a non-default location.
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
Rerun the installation.
