New Zip File for B50 software

I downloaded the Zip File for the new software but it won’t open for me, is there a problem with it?

The archive should be opened and the file with the firmware transferred to a flash drive no larger than 4 gigabytes, first it should be formatted in FAT16 or simply FAT, but not FAT 32 or exFAT. Open the go control application and it will recognize the new firmware, press the agree button and within one We don’t touch anything for a minute, the firmware update process takes place automatically.
