I have a client with 9204 installed on Windows XP. SQL*Net to a 9204 db works fine. ODBC fails on connection test with: Unable to connect: SQL_State=IM004. [Microsoft][ODBC Driver manager]Driver's SQLAllocHandle on SQL_HANDLE_ENV failed. I downloadsed the 9206 odbc driver from otn and installed that version, but still receive the same error. Any ideas please? Thanks -- ..
