Go online and search for microscopes that appear to be physically identical to your microscope.
May be the same microscope but just branded differently. I.e., the hardware and software (drivers) will work for that product and maybe for your microscope as well.
Google "MY-V020 Digital Microscope" and select images. I found a couple of brands that appear to match.
AmScope, Bysameyee perhaps.
No harm in downloading and trying the drivers. Start with the newest drivers and work back a couple of versions if necessary.,
