I'm trying to install TTW on a new (used) laptop I picked up (2.5GHz Core i5, 4GB ram), but I keep getting this error. I already have the newest version of C++ runtime (Visual C++ 2013 Redistributable x64 and x86 12.0.21005) and I've tried uninstalling and reinstalling it, but I keep getting this same error. C++ runtime seems to work fine with other programs that require it (eg with PPSSPP, a PSP emulator; it gives a similar error if I don't have C++ runtime installed). I'll hop on my laptop in a minute and paste my most recent log in a minute here.
[edit] Here's the log, but I don't think it'll help much since all it mentions is not being able to find Fallout3.esm, which the installer complains about after the missing DLL error:

Side not on Fallout3.esm: I've tried just copying my regular Fallout3.esm and dropping it in that folder. The installer gives the same missing DLL error and then complains that it can't find "Fallout3.esm.new" instead.
