I have an error: "Driver's SQLAllocHandle on SQL_HANDLE_ENV Failed" that appears when I try to connect to Oracle Database using MS Excel. Odbc connection works and can connect. I have read up on FAQ on Oracle and have tried the following suggestions:
1. Re-Installed Oracle Client, not working
2. Checked PATH env variable, it is correct
3. Checked and changed permissions, not working
When I use the test on my ODBCAD32.exe, it works and can connect. Even PL/SQL Developer client can connect to Oracle. It is just MS Office and Qlikview that does not want to connect. Qlikview gives me the following error:
"SQL##f - SqlState:IM014,ErrorCode:0, ErrorMsg: [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application"
