Issue installing ODBC driver for Oracle

edited May 7, 2013 5:54AM in Database Install/Upgrade/Opatch (MOSC) 2 commentsAnswered ✓
I needed to install an ODBC driver for Oracle on a 64-bit Windows Server 2008 machine. Per information I got on metalink, I needed to download and install Oracle Client for 64-bit : win64_11gR2_client

So that's exactly what I did. Installation ran smoothly, I modified the tnsnames.ora file to add an entry for a particular database and everything looked good. Then I tried to create on ODBC connection and if I use odbccad32 from C:\Windows\SysWOW64\odbccad32.exe, I do not see Oracle in OraClient11g_home1 driver there, but I do see it if I run C:\Windows\system32\odbccad32.exe.  Can someone explain to me why is this happening? I did download and install the driver for 64-bit, why is it coming up as 32-bit? 

Howdy, Stranger!
