EX4 to MQ4 for MT4

HELP!
there are a series of ex4 files I'd like to install on a MT4 platform
my computer says file not recognised and after hrs of attempting various ways I still can't get the indicators to work
sorry it's probably simple as but...
there must be a way and I don't wish to play with/change or resell said indicators (seen many times it's illegal but there must be a way)
I just want to use them and they are all from Davits pivot thread

there is so much to learn
got it
that kick in the bum from Davit has me rereading his thread with way more attention
and doing another PA course
been around since 2012 with a few A/cs with forgotten passwords, past names Nimbinsstoned and stonedfish
this time I will get my head around this

You do not need mq4 file
But you need the ex4 file - hence just copy the ex4 file to appropriate folder

sorry I got it with the post above yours
thanks for your help
I've survived 2 comas and some things just take a little longer to get through the fog
I'll prob do a journal soonish (after current trades closed) if you care to look and critic it
