You will need to run it on your 32 bit emulation, as the program is simply not compatible with 64 bit windows programs. Inside of the folder, there is a file entitled “sigdb400.sbs”. If your DSP4000 is any other version than 2.158, delete this file and use the MIDI-> get database function to pull the database from your 4000.
Make sure to download all five files, and place them all in the same folder.
Hope that helps!
