Can I install both a 32-bit and 64-bit Oracle Client 11g R2 (both same 11g R2 version) in one Windows 7 64-bit Operating System machine? I installed the 64-bit client already, but when I try to install the 32-bit client, it jsut hangs or freezes or does not continue.
Turn Off the Windows 7 UAC (User Account Control):
1) Go to Windows Start menu | under the Search field | type: UAC
2) Move the slider bar to the lowest (disable notifications or never notify)
3) Restart computer
4) Try the installation again
5) If you prefer, turn the UAC back to its previous setting after the installation.
