Invalid Setup Language Error ( BOBJ client Install 4.1 SP04)

Hi,

I download the client tools files from market place for BOBJ 4.1 SP04. When i run the install it shows up the pop up box to select language

It is showing up with # sign e.g. #en# and even the ok and cancel button have # signs with them, when i hit 'ok', it shows up the error "Invalid Setup Language validation error".

Any ideas?
