Rhinoceros 4.0 dando erro ao abrir

Ciao,
there is another post where a user with rhino 2.0 has problems loading the program.
Could be that you are in the same situation.
Try running the program in compatibility mode

Rhinoceros 2.0 question - crashes and then gives error message

Imho, as suggested by Nosorozec, a “safe” way to use old software is to make a virtual machine with old SO (win 7.0 or XP) and run there Rhino 2.0. This would protect you from new updates that could break old software.
