Why is the Unreal Build tool getting these errors?

A bit of a vague question, but I don’t really know how to describe what’s going on. I’m trying to make a HTML5 game with the source version of 4.6.1. I have done this previously, within the last month, but now it won’t work. It is telling me that it can’t find random Physics stuff or something isn’t declared. I haven’t touched any of those files. The WindowsNoEditor development build of my new project works just fine. I have rebuilt the whole engine in Visual Studio and that didn’t do anything. The only thing that has changed since I last used this successfully is that I cloned my hard drive onto a new one. The error messages are pointing to the correct hard drive, but it’s just something to keep in mind. I can’t work on it again until tomorrow morning, when I’ll try to find those files it’s talking about. Just wasn’t sure if this is a common error.

I’m attaching my UnrealBuildTool log, and here is what it is showing in red.

I’m going to update this with my findings. I have a second computer that does not have this issue and I’m remembering some past experiences where I’ve had this happen before.

My other computer works fine for web builds, but this one gets these same errors for any project when trying HTML5.

I was using a custom profile to choose all my settings, but using the premade Firefox 32-bit (and others) profile works just fine. I don’t know what could make it different, but everything goes just swimmingly with any version of the typical profiles. I don’t know if this is a bug, since my more recent build of the source on my other computer works.
