A heap of warnings and no image on the welcome/finish page

Question

This is my first time using NSIS and I'm trying to make an installer that uses MUI2, but it's not going too smoothly. When I compile my code I don't get any errors, so it compiles, but I get a truckload of warnings. First it happened with a slightly complex installer, but I even made a super-simple one (still using MUI2) and I still get the same errors. This is the resulting log:

In addition, no image displays on the left side of either the welcome or finish page, although I suspect that's connected to the above warnings. Basically, I'd like to know what the problem is and how I should fix it. If anybody needs the code of my .nsi file please say and I'll add it to the question.

I'm running Windows 7 Home Premium (if that helps) and using the latest version of NSIS (2.46).

Answer 1

Well, I took a careful look at an example and saw that I hadn't inserted the MUI_LANGUAGE macro in my code, which I didn't know was required. It fixed both the warnings and the disappearing welcome/finish images. In my opinion it's kind of strange that it's required, but that's how it is anyway. Hope this helps anyone with the same problem.
