Hi Kosu,
We could not replicate the transparency problem - the control was tested on both Windows7 32 and Windows764 bit with the following code:
nChartControl1.Settings.TransparentBackground =
true;
nChartControl1.BackgroundStyle.FillStyle.SetTransparencyPercent(100);
nChartControl1.Settings.TextRenderingHint = System.Drawing.Text.TextRenderingHint.AntiAliasGridFit;(it is important to set the text rasterization hint to antialialias because ClearType rendering cannot be achieved on alpha blended images).
Regarding the license key manager - this is by design - the manager stores the license key in the registry and has to be run from an account that has permissions to modify it. You can also apply the license key trough code as described in the documentation.
Questions or comments - please feel free...
