Re: The Sims 3 > Incomplete Installation ("launcher has stopped working", etc) Help Needed (FIVE days and no response? Really?)
I solved the problem myself, actually. It's a simple matter of putting the d3dx9_31.dll file into the sims _Installer folder.
You can get the file all over the internet. I don't know why this isn't in documentation or standard help yet, they said that they would do it so this issue doesn't happen to others.
