Hi Angela, You mentioned ODBC connections Have you checked that your application is using the 32bit ones? On a 64bit system you have 2 ODBC connection ²possibilities²: 32bit and 64bit 64bit: c:\Windows\System32\odbcad32.exe (!) HKEY_LOCAL_MACHINE\SOFTWARE\ODBC 32bit: c:\Windows\Syswow64\odbcad32.exe (!) HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ODBC The odbcad32.exe really are switched, so watch out for that!
