          Are you sure your ODBC connection is 64 bits ?

          Did you set your TNSNAME.ora and SQL files correctly ?

          To test it you can double check with Excel for example.

          I'm able to make it work using Win 2003 64 Bits after installing the correct ODBC driver (64). So I guess this could be the issue..

            You can find the 64 bit Oracle 10g Client here: http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201winx64soft.html

            If your database is earlier than 9i you might have a problem. I could not find a 64 bit driver that would work with Oracle 8.0.5 and the 32 bit driver would not work with QlikView, either 32 bit or 64 bit, installed on a 64 bit machine. I resorted to extracting on a 32 bit machine and copying the QVDs to the 64 bit machine with a scheduled batch file.

            Good luck...

                  I just saw your post.

                  Firstly i reinstalled my oracle client

                  In my PC (Dell Win7 64bit), ODBC Data Source Administrator is in different folder.

                  I found ODBC Data Source Administrator in this path: C:\Windows\SysWOW64\odbcad32.exe

                  redefine my data source then the problem is over.

                  If something obsess you, please ask me...

                  Best Regards...

                      Hello Selcuk,

                      In addition to this, if you are using QV version 9, you will need to have both 64 and 32 bits versions installed, since in QV 9 64 you cannot access to 32 bit ODBC sources and otherwise.

                      Installations can coexist if you install them in different folders.

                        Hi, How did you redifine? I have the same problem. 64 bit odbc drivers are not seen through 32 bit odbc programs. I have to odbc programs as follows.

                        C:\WiNNT\SysWOW64\odbcad32.exe - 32 bit drivers

                        C:\WINNT\system32\odbcad32.exe - 64 bit drivers.

                        I am unable to load using publisher.It gives following error
