Hello ! Im trying to make a PC game and i need a installer,but i want to design the installer. Please Help me ! ! !
check this List of installation software - Wikipedia 
Be more specific. If you’re talking specifically about windows, try http://nsis.sourceforge.net/Main_Page
If you want a ‘cross platform’ solution you may want to try packing your game using cmake, but it is more complex CMake Wiki has moved
.zip files are best for freeware. It’s easy to make, easy to give, and makes the file a tad bit more compact.
For Pay to play, I’m pretty sure your publisher can handle that :\ If your indie, you can have them pay you in PayPal or something, then give them a code or something, like Minecraft does, but other than that I don’t really know 
Game Installer! For PC, use WiX, it’s your best chance, for Mac, its already integrated. I don’t know about Linux.
Oh well, good luck
