I am using Windows Millennium (Windows Me) and ChemFinder does not work properly in Search mode. After drawing a structure in ChemDraw for the query, when I switch back to ChemFinder, I get an error message similar to:
Failed to establish advise loop with DDE Server.......DMLERR_INVALIDPARAMETER.
ChemFinder 5.1.2 and below were developed before Windows Me. They are not compatible. The latest version of ChemFinder is compatible with Windows Me. Upgrade to the latest version.
