Grasshopper 0.9.76.0

Hello

I had Grasshopper 0.9.75.0 more than one year, I was in my User/downlaod folder, with many other files, and worked perfect, yesterday i downloaded Grasshopper 0.9.76.0, in the same folder, and deleted the old 0.75 version, (it is still in the recycle.)

Today i restarted pc severel times, but when i start Rhino and grasshopper, it continue to load the old version, of Grasshopper 0.9.75.0 , what i did wrong ?
