many people do not no where rune ed is so here we go:
First you must find your rune folder. Look for a folder in your C drive(my computer>harddrive c) called Rune or RuneHOV, if it isnt there then check the folder Program Files (also located in the C drive) for Rune Or Rune Hov
once youve found the Rune Folder click on it and many more folders open the folder called "system" Rune ed is in your rune system folder and is labeled as RuneEd.exe (should have the same icon as rune does)
once uve found RuneEd.exe your set to make maps and other things, most people have errors when they first start rune editor, to fix this refer to my other tutorial.
