ODP.NET

I have a Windows 7 64-bit. I would think that using 32-bit Java, 32-bit Oracle Client and 32-bit ODAC would work just fine on this operating system. However, I had no luck getting it to run. Here is what I did and a few reasons why I prefer to never work with Oracle products:

Installed 32-bit JDK/JRE (1.6 Update 25)
Installed 32-bit Oracle Client (11g R2) Home 1
Tested connectivity from SQL Developer successfully
Installed 32-bit ODT (11g R3) to Home 1 (installer noted upgrades and new installs)
Failed connectivity from all things windows (ODBC, ADO, ADO.Net)

Uninstalled 32-bit ODT
Failed to uninstall 32-bit Oracle Client Home 1 (oraparam.ini file missing among other issues)
Installed 32-bit Oracle Client (11g R2) Home 2
Failed to uninstall 32-bit Oracle Client Home 1 (told to use deinstall tool)
Failed to uninstall 32-bit Oracle Client Home 2 (told to use deinstall tool)
Failed to run uninstall tool in Home 1 (told to download standalone deinstall tool)
Uninstalled 32-bit Oracle Client Home 2 (completed successfuly with errors - seriously?)
Uninstalled 32-bit Oracle Client Home 1 (completed successfully, but couldn't delete folder)
Oracle.DataAccess and Oracle.Web are still installed in GAC. Uninstall attempts fail (access denied)
Installed 32-bit Oracle Client (11g R2) Home 1
Tested connectivity from SQL Developer successfully
Tested connectivity from .Net 3.5 successfully (using 32-bit 2.0 dll)
Tested connectivity from .Net 4.0 successfully (using 32-bit 2.0 dll)

Does anyone have any suggestions on getting Oracle Data Tools for Windows to work before I try that again?
