The exception is thrown here:

        alias TypeTuple!(GENERIC_READ,
                FILE_SHARE_READ, (SECURITY_ATTRIBUTES*).init,

        auto h = CreateFileW(std.utf.toUTF16z(name), defaults);

        cenforce(h != INVALID_HANDLE_VALUE, name);    // <-- HERE

It seems to be related to a Unicode encoding issue, possibly the 
encoding that the console is using. (I am assuming that getfilename() 
reads from the console.)

It could be about file access rights as well.
