[INS-75012] Software Location specified is already an existing oracle home and does not contain the selected oracle Goldengate install type

[INS-75012] Software Location specified is already an existing oracle home and does not contain the selected oracle Goldengate install type

Problem:- 
While installing oracle goldengate we got an error [INS-75012]  while selecting an oracle Goldengate home.

Reason :- 
The specified directory is already used by an existing deinstalled/improperly removed goldengate Home and oracle central oraInventory inventory.xml file contains the goldengate home information.

[oracle@vm2 ContentsXML]$ cat inventory.xml

Solution:- 

Invoke runInstaller to remove the oraInventory information from oracle central inventory.

Example:-
[oracle@vm2 ~]$ . oraenv
ORACLE_SID = [targetdb] ? 
The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1 is /u01/app/oracle
[oracle@vm2 ~]$ cd /u01/app/oracle/product/11.2.0/db_1/oui/bin/

[oracle@vm2 bin]$ ./runInstaller -silent -deinstall REMOVE_HOMES={"/u01/gghome"}

Repeat the steps by replacing ORACLE_HOME in REMOVE_HOMES and remove the unwanted Goldengate home and try the installation again.

now inventory.xml file

[oracle@vm2 ContentsXML]$ cat inventory.xml

cancel the installation and Starting the goldengate configuration again by invoking runInstaller

Hope, this helps you.
