I installed the doc viewer, with no problems reported.
If I try to run a demo in the Sample Center I get the error: This demo cannot be compiled. The VS.NET has not installed on this machine..
If I run the control installer, it reports that all controls were successfully added into the Visual Studios toolbox.
If I create a forms project in Visual Studios (VB) no Spire controls show up in the toolbox.
I am able to load the demo projects into Visual Studio, and they run correctly, but I notice there is nothing specifically for VS 2017, which I'm running. Is it a version compatibility issue?
