You need to..
download the vbrun300.dll from Mick's page, and when it unpacks itself to whatever folder you have. For me, all of my downloads are in my C:/downloads folder, so I have everything all there ready to find/look at.
But the vbrun300.dll will unload somewhere, so you need to find it, and put it in the same folder as the corn snake predictor stuff. The program won't run unless that .dll file is in the folder as well. I made a folder in my program files, called Corn Snake Genetics, and extracted the predictor there, and then moved the .dll file there as well.
So you need to find where it stashed your .dll, and just manually move it to the folder you've set up.
Hopefully you understood all of that. =P
