The suite uses the wininet.dll, crypt32.dll and advapi.dll libraries. All these dlls are binded at run-time. So if some of these dll does not available on destination PC then features implementing by that dll will not work. All latest versions of Microsoft Windows always have wininet.dll, crypt32.dll and advapi.dll libraries installed as they are became core part of the Windows. So theoretically you might have problems only with Windows 95 since it came out with preinstalled IE version 4.0 and even if this case you can simple install latest version of IE to fix it.
