I get "microsoft.jet.oledb.4.0" not registered and there is no MDAC or "microsoft.jet.oledb.4.0" that I can install? Everything else I have downloaded and installed runs fine as well as the applicaiton I am building.
Having the code of the samples on my machine (with Windows 7 x64), I just opened the project corresponding to the features I wanted to look at (currently WinChart), changed the target plateform from "Any CPU" to "x86", and recompiled it. Now it works fine.
