flyctl not working on Windows with wintun error


I have installed the latest flyctl for Windows (with no error) but when I execute any command, it’s just bug. I have two other apps using wintun: wireguard and tailscale. I’m on Windows Pro 20H2.

panic: Error loading wintun.dll DLL: Unable to load library: The specified module could not be found.

goroutine 1 [running]:*lazyProc).Addr(...)
        /home/runner/go/pkg/mod/ +0xad3

We’re working on a fix for this! Here’s a workaround you can use for now.

A fix to run the latest release is to download wintun.dll from and place it in %homepath%\.fly\bin

This is fixed in the latest flyctl update.
