PT: Problemas com o FOP2

Bom dia!

Tenho o habito de instalar a versão gratuita do fop2 para que meus clientes testem. Na maioria das vezes utilizamos uma plataforma de desenvolvimento nacional chamada SNEP. Eles até possuem um tutorial para instalação na central deles. Acontece que só funcionou uma vez pra mim. Em dois clientes estou com ele bugado:

Cliente 1 - Instala normal, mostra tudo como ativo, rodando, mas os botões de discar, de transferir... não funcionam.

Cliente 2 - Instala normal, mas não consigo colocar o serviço para rodar.

root@snep-3:~# /etc/init.d/fop2 restart
Restarting Flash Operator Panel 2: fop2start-stop-daemon: unable to start /usr/local/fop2/fop2_server (No such file or directory)
root@snep-3:~# /etc/init.d/fop2 stop
Stopping Flash Operator Panel 2: fop2No process in pidfile '/var/run/fop2.pid' found running; none killed.
root@snep-3:~# /etc/init.d/fop2 start
Starting Flash Operator Panel 2: fop2start-stop-daemon: unable to start /usr/local/fop2/fop2_server (No such file or directory)

root@snep-3:~# service fop2 restart
Job for fop2.service failed. See 'systemctl status fop2.service' and 'journalctl -xn' for details.

Gostaria de uma ajuda, pois na maioria das vezes os clientes optam por realizar a compra do produto após utilizar a versão gratuita, mas eu para isso, eu preciso que a versão gratuita funcione.
Qualquer informação adicional necessária estou disponível para passar.

EN: Problems with FOP2

Good Morning!

I have the habit of installing the free version of fop2 for my clients to test. Most of the time we use a national development platform called SNEP. They even have a tutorial for installation in their central office. Turns out it only worked once for me. On two clients I'm bothered with it:

Client 1 - Installs normal, shows everything as active, running, but the dial, transfer ... buttons do not work.

Client 2 - Installs normal, but I can not get the service to run.

root@snep-3:~# /etc/init.d/fop2 restart
Restarting Flash Operator Panel 2: fop2start-stop-daemon: unable to start /usr/local/fop2/fop2_server (No such file or directory)
root@snep-3:~# /etc/init.d/fop2 stop
Stopping Flash Operator Panel 2: fop2No process in pidfile '/var/run/fop2.pid' found running; none killed.
root@snep-3:~# /etc/init.d/fop2 start
Starting Flash Operator Panel 2: fop2start-stop-daemon: unable to start /usr/local/fop2/fop2_server (No such file or directory)

root@snep-3:~# service fop2 restart
Job for fop2.service failed. See 'systemctl status fop2.service' and 'journalctl -xn' for details.

I would like a help since most of the time the clients choose to make the purchase of the product after using the free version, but for this I need the free version to work.
Any additional information I need is available to pass.
