Are you sure about that. Since both homes are in the "path", wouldn't the application find the Oracle client listed first? >>> Niels Jespersen <NJN@xxxxxx> 10/30/13 3:37 AM >>> 32-bit and 64-bit client coexist fine. 32-bit applications only "sees" the 32-bit client and 64-bit apps only "sees" 64-bit clients. Have both in the path. /Niels -----Oprindelig meddelelse----- Fra: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] På vegne af Jeffrey Beckstrom Sendt: 29. oktober 2013 20:13 Til: oracle-l-freelists; oracle-db-l Emne: Oracle 32-bit and 64-bit client on Windows We have a need to have both the 32 and 64 bit clients installed on a Windows 7 PC. In order for the 32-bit application to access the 32-bit Oracle client, due we have to alter the search "path" prior to invoking the 32-bit application or will it magically know to use the 32-bit Oracle dll's?
