Herelink flasher problem

Hi I need a help regarding flasher of herelink.
Whenever I try to flash the firmware it gives me a error

Same as in the image

I’m facing this issue and the official dealer of herelink in India says I can’t help you out.

Can you please tell me how you flash your herelink?
Is that a remoter or the airunit?
Where did you place the flasher_win, please makesure the file is not read-only ?
Did you install the correct drive for the device?
You can check this link and follow these processes to flash your herelink
