MiniWas 620, External Harddrive...

Hi all, I have a new issue with my MiniWas 620 here. I am trying to reinstall the mniwas on my new laptop and ditto external harddrive. All goes well until I reach 91% and a database registration error occurs. There are plenty of threads on this error but I have the following question. Is it possible to install both the WAS as well as the DB on my external harddrive (G:)? Running the installation the DB was installed there but the WAS was installed again on my laptop harddrive C:. How can I change that since I think that is the problem. Thanks, Tiest.
