Your screenshot suggests that the test for MOSS 2007 WSS 3.0 failed and this means that the system on which you are trying to install EDRSMS doesn't have WSS 3.0 installed. I suggest you check whether WSS 3.0 is installed on the system. I think you have only installed service pack 1 and not the actual windows sharepoint services 3.0. Please check and try again.
I hope this helps.
Thanks & Regards,
