First, write as normal sentences and paragraphs. it's a bit confusing trying to read the way you have it.

You need the M4 base first. H4 will not work without it.

Install M4 to Poser 7 and let it initialize on install or use the desktop icon after install.

Now if you are trying to install in a runtime that is not in Poser, you need to make a dummy folder first. Copy the Poser .exe to that file. Then everything will install.

Now you can install H4 to that folder. Don't forget to initialize H4.

Then you can either move that runtime to where you want or just add it to your runtime list in Poser. Don't forget to delete the Copy Poser .exe before you start poser up or strange things can happen.
