I can't upgrade any VKB product

[pablete]

Hello,

I have just purchased the VKB Rudder pedals and I,m trying to connect them to the black box of my VKB Gunfighter.
I can't update the firmware because every time I run the Bootlader I receive this message warning: Z-Bootloader-C.exe not found. You must run it manually
What am I doing wrong?

Thank you

Sorry, I was using the old Bootloader.exe, that's why it was not working.
Now it runs correctly.
What is the file corresponding to GunfighterII?
Thanks
