Thanks: 1 times

Hi, as in "Printer class, Install" section, I have tried to program as tutorial, but get the following error:

Exception thrown: 'Leadtools.RasterException' in Leadtools.Printer.dll
Leadtools.RasterException: Function not successful
at Leadtools.Printer.PrinterDriverException.CheckErrorCode(Int32 code)
at Leadtools.Printer.Printer.Install(PrinterInfo printerInfo)
at MDSVirtualPrinter.src.PrinterWorker.InstallMDSPrinter(String name) in W:\DEV\VS2017\MDSVirtualPrinter\MDSVirtualPrinter\src\PrinterWorker.cs:line 152

Could anyone help to solve this problem?
I'm using C# library, .Net 4.6, Visual studio 2017.
Any suggest would be appreciated.

Adding a virtual printer requires registry access. Could you ensure the instance of Visual Studio you're developing in has been launched with administrator rights?
