Help with 'downgrading' software/uninstall problem 6.04

Hi Folks,

I am currently trying to 'downgrade' our Congo software from version 6.0.4.9.0.82 to our previous version 6.0.3.9.0.73...... but the desk is not letting me install the previous software and keeps coming up with the message - you must uninstall 6.0.4.9.0.82 before you can re-install the older version.................any ideas on how I can do this without it all going a bit wrong?!

Many thanks for any help provided!

Matts
