Do I understand you properly, if I install the 64bit MS Visual Studio in the computer, the problem will be solved ? MS Visual Studio is now free, so this is for me no extra costs option.
You will need Visual Studio for programming in C++, but not for merely running Zorro. The VC++ runtime would solve your problem. But we prefer no runtime installation for the 32 bit version, so we want to include the dlls directly. We had not had a PC so far where the 32 bit version would require a runtime. What's your Windows version?
