Acess hana data source fail with 1033 error

Hello,

I installed a SAP BO analysis for excel 2.1  (32 bit)  on my station (office 32 bit with hana client 32 bit).

when I try to add a data source I have this error "1033 ERROR WHILE PARSING PROTOCOL"  We use Hana SP9 MDC.

I have already created a data source with Hana SP8  and it works fine is there a bug in Hana SP 9 MDC

Thanks
