You are giving an instruction on what do to after something in the future has occurred.
The correct option is:
Once the installation finished, click on start
Once the installation has finished, click on start
Once the installation has been finished, click on start
You must say "once the installation has finished" because at the time of the instruction, it has not yet finished.
The expression "has been" is only appropriate is something has been used up by something or someone.
For example, you might say:
"After the cake has been finished, clear the plate away"
That's because the cake didn't do the finishing - it was finished by those who ate it.
As you are speaking directly about the installation, which completes by itself, just say it "has finished".
