Can I get the metatrader4.exe for general and several brokers? 

One of my broker's MT4 doesn't apply for signal tap in demo accounts. 

So I need MT4 program for all brokers. 

In MQL5, When I subsrcibe signal, I can download MT5 only. 

How can I download MT4?

MT4 is for any brokers which are supporting MT4.
If you downloaded MT4 from your broker and can not connect this MT4 to the other broker so it means the following:
the other broker is psoposing the openning account directly on their website.

----------------
Alternatively - you can use "clean" MT4 from this post #11 but it is same procedure about the brokers: if the broker does not allow to open account directly from Metatrader so it means that this broker wants for us to go to broker's website for the account.
