I am using multibit classic 0.5.19 which I can export the private key in text. I think I do not need to download wallet-key-tool the file from github and only need to download the  tool on Windows to make a qrcode from the text private keys: https://sourceforge.net/projects/zint/
Correct?  For answer which lead me to successful claim the BCC, I will reward 0.05 bitcoin, please leave your bitcoin address.
