Confirming

Just before the crash there's a call to: 
00d4:Call kernelbase.GetSystemWow64DirectoryA(08c34684,00000008) ret=1440836ac
00d4:Call ntdll.RtlInitUnicodeString(009afbf0,7b08fc40
L"C:\windows\syswow64") ret=7b017cae
00d4:Ret  kernelbase.GetSystemWow64DirectoryA() retval=00000014 ret=1440836ac

If you put a hack in kernelbase so that that call fails, the application starts
fine for me; I guess maybe a different code path is than chosen (?)

Looks like it might have to do with wow64 support (?)

Hack to make the program start:
