Export op results in error "EXP.EXE has encountered a problem and needs to

I have been working with Oracle Designer on an old computer (running Windows 2000 and an Oracle 10.2 database) and I am attempting to get it to run on a newer computer (running Windows XP and an Oracle 11g database (release 11.1.0.6)). Regarding the Designer version, I installed the same version (9.0.4.3) that was running on the old computer. On the new computer, features of the tool have worked (ER Diagrammer, DB Design Transformer, Design Editor), but the Export operation of the Repository Admin Utility did not work. When I attempted to run Export, the following happened:
(1) The "Save As" dialog was displayed (as expected).
(2) A EXP.EXE script window opened for the Export command and displayed the following:
Export: Release 9.0.1.5.1
Connected to: Oracle Database 11g Enterprise Edition Release 11.1.0.6.0
Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set
(3) Immediately, an error dialog appeared stating "EXP.EXE has encountered a problem and needs to close. We are sorry for the inconvenience."

I am testing Export so that I can test Import, which is the operation I will need to load data from the old computer.

Any ideas how to fix this problem?

If it can't be fixed, are there other ways of transferring data from one repository installation to another?

ANSWER:

add the 11g client to the pc and then modify the registry so that it points to the imp and exp from the 11g client.
