Hi,
We are being asked from time to time for errors when viewing the CHM documentation of CUDA.NET or OpenCL.NET.
Usually there is an “Internet Explorer” like message stating the page cannot be displayed.
This happens because of Internet Explorer security configuration that blocks CHM content when opened directly from the Web.
The best way to resolve it is to download the ZIP file to a safe folder on your computer (not temporary internet folders), unzip it and then open the file outside of Internet Explorer itself.
This should resolve the more in most of the cases.
