Can you tell me which version of MMConvertGUI you are
using? In addition, what is your windows version? WinXP or
Win2000, MMC only support Win2000+sp4, WinXP+sp2 and
Win2003+sp1+MSI 3.1.
what is the missing DLL? its name?
if you are trying install on Win2003 without sp2, pls
download latest MSI 3.1(Microsoft Installer) from
microsoft's download site, then reinstall MMC.
sorry for late reply.
