In a 64 - bit Windows:
64 exe and DLL in the directory c: \ Windows \ sys tem32 directory.
32 bit exe and DLL in the directory c: \ Windows \ sys wow64 directory.
So pay attention to:
In win64 system registered under 32-bit ocx DLL to 32 ocx or copy the DLL to the c: \ Windows \ syswow64 \ directory,
And registered to c: \ Windows \ syswow64 \ regsvr32 XXXXXXX ocx or DLL
Under win64 a system set up 32-bit programs use a database alias to c: \ Windows \ \ syswow64 \ cliconfg exe
Under win64 a system set up a 32-bit application system DSN to c: \ Windows \ \ syswow64 \ odbcad32 exe
