Oracle Developer Suite 10g cannot be installed into existing Oracle Home
 
I downloaded the latest Oracle versions for studying. (I don't have a metalink account because I am actually not working)

I want to install Oracle Database 11g + Oracle Developer Suite 10g on the same Windows XP Desktop. I did the following steps :

- Install Oracle Database 11g in ORACLE_HOME "C:\oracle\product\11.1.0\db_1".
- Create a database DEV
- Startup database DEV, listener and configure sqlnet.ora+tnsnames.ora
- Connect to the database with sqlplus system@dev => connection succeeded
- Install Oracle Developer Suite 10g in ORACLE_HOME "c:\oracle\product\DevSuiteHome_1" and choose Installation Type "Complete (1.13 GB)"

When I install Oracle Developer Suite 10g I receive the following error:

Oracle Developer Suite 10g (10.1.2.0.2) cannot be installed into existing Oracle9i 9.2.0.1.0 or higher Oracle Home.

I don't understand why I receive this error. Oracle Developer Suite creates a separate Oracle Home, so I don't understand why the error says that it tries to install into an existing Oracle Home.

What must I do to solve this problem?

hi... you are trying to install oracle developer suite in the same folder as where you installed oracle database. select a different folder location and you should be fine.

I tried to install to folder "c:\DevSuiteHome2". But I still receive the same error.

Any oter suggestions?

See here some supplemental information.

Before installing Oracle 11g database I deleted the registry entry HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE completely. So it's not a registry problem.

Actually the registry entry HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE only contains the entries "KEY_orahome11g" and "SYSMAN". "KEY_orahome11g" is the Oracle home from Oracle 11g database.

In the documentation I only found a section "Preventing Conflicts With Other Oracle Homes" but it only applies to Linux and Solaris, NOT to Windows.

Any other suggestions?

You need to delete c:\program files\oracle as well. The installer keeps an inventory in there.
