This is a bug in the DSP Builder installer from that version. Unfortunately it finds the registry keys for your old version of MATLAB (which MATLAB doesn't remove for some reason when it's uninstalled) and aborts before checking if there is another version of MATLAB instead.

To work around this, load regedit (Start->Run... and then type regedit). Then select HKEY_LOCAL_MACHINE -> SOFTWARE -> MathWorks -> MATLAB. Now you should see a couple of version numbers. One will be for R2007a (7.4), and then you should have your old one (6.0). Right click on 6.0 and click delete.

Hopefully the DSP Builder installer should now work.
