I'm trying to get Excel '97 to work with Labview 6.02, but I'm always receiving error message: -2147319784: "old format or invalid type library". I modified windows registry as told in LV knowledgebase. After that I could see Excel components in ActiveX pull down menus. I have tried to run demos such as "Open Excel And Make visible.vi" but they always output the error message. I have tried this with both Windows 2000 and NT. Other programmes, for instance MS Access, seem to work fine. What is the catch?
