davidonpda，你之前也是跑的 laszlo 构建吗？
davidonpda, were you also running laszlo's build previously?
检查 "%appdata%" 目录是否存在，以及 "%appdata%\bitcoin"
Check if the "%appdata%" directory exists, and "%appdata%\bitcoin"

rename "%appdata%\bitcoin" bitcoin2
rename "%appdata%\bitcoin" bitcoin2
那样能行吗？
does it work then?
