Serz.exe issues

I’m trying to use serz to mod a certain locomotives headlight flares, in order to edit bin files I’m pretty sure you need serz?
Everytime I drag the bin file over serz.exe I keep getting a system error (stlport_vc10.5.2.dll was not found) and saying reinstalling the program may fix the issue. But ever since 2013, the first day I got train simulator serz has never worked for me?? Is there something I’m missing or what? Any help is appreciated
And right after that error message I get another one saying “ The code execution cannot proceed because zlibwapi.dll was not found.”
