Cria novo arquivo CSV + JavaFX + Windows + jar

Bom dia pessoal. Tenho uma aplicação java desktop(javaFX)que salva alguns dados de configuração em um arquivo CSV. O jar da mesma funciona perfeitamente tanto no OSX quanto no Linux, porém não no Windows, pelo erro acredito que eu esteja parametrizando de forma incorreta o diretorio, mas não me lembro de outra maneira e nem encontrei(ja tem uns 8 anos que não colocava a mão no Windows).

Segue abaixo código do trecho:

Path ARQUIVO_SAIDA = Paths.get("dados.csv");
    private void salvaDados() {
    StringBuffer sb = new StringBuffer();
    for (Configuracao c : contas) {
        String linha = criaLinha(c);
        sb.append(linha);
        sb.append(System.getProperty("line.separator"));
    }
    try {
        Files.delete(ARQUIVO_SAIDA);
        Files.write(ARQUIVO_SAIDA, sb.toString().getBytes());
    } catch (IOException e) {
        e.printStackTrace();
        System.exit(0);
    }
}

também tentei utilizar o seguinte caminho(no caso acima o arquivo está no mesmo diretorio que o jar)

private static final Path ARQUIVO_SAIDA = Paths.get("C:\\PastaSistema\\dados.csv");

E retorna o seguinte erro:

Ja dei permissões nas pastas até com o usuarios Todos e permissão total. Acredito que seja um erro bem idiota.
