I am currently investigating the possible issues when migrating from Windows XP 32bit to Windows 7 64-bit. The scope is MS Excel (32-bit), MS Access (32-bit) using VBA/Macros addins, ODBC and all related issues.
For example: if you use excel (32-bit) and oracle 32-bit odbc driver. There is an issue described at: http://www.dbmotive.com/oracle_error_codes.php?type=ORA&errcode=6413
are there any (other) known issues / resources / websites / tools about this ?
