Failed to load 'PI Point' PlugIn

I have developed a little Excel AddIn where I use the AFSDK.dll (v. to display different AFValues. To collect AFValues I use the AFAttribute class in combination with the methode GetValue. AFAttribute.GetValue().


On my machine everything works fine (I have installed several PI Products like PI SMT, PI System Explorer, PI Processbook, ...). Now I have installed this Excel AddIn on another machine. On this machine I can connect to the AF System but when I read out the value of an AFAttribute where the DataReference typ is  PI Point I always receive the error message: "Failed to load 'PI Point' PlugIn. The PlugIn Type 'OSISoft.AF.Asset.DataReference.PIPointDR' was not found". In my Visual Studio project I have only one special reference and this one is OSIsoft.AFSDK.


Does someone has an idea what the problem is and how to solve it?


Second question. When I use AFSDK functionality on a machine where no OSIsoft PI product like PI System Explorer is installed which product should I install to avoid such problems as described?
