我正在使用Spire.pdf动态链接库静默地打印html页面，它在我的机器上工作得很好，但在客户机上给出了下面的错误。

我看了下面的页面，尝试通过添加引用和将dll复制到可执行文件所在的本地文件夹来引用mshtml.dll，可能是我不完全了解如何使用它。

Could not load file or assembly 'Microsoft.mshtml ... Strong name validation failed

如果有人能告诉我如何在客户机上安装dll，下面是我正在使用代码

                Dim doc As New PdfDocument()
                Dim pgSt As New PdfPageSettings()
                pgSt.Size = PdfPageSize.A4
                pgSt.SetMargins(0.5, 0.5, 0.5, 0.5)

                Dim htmlLayoutFormat As New PdfHtmlLayoutFormat()
                htmlLayoutFormat.IsWaiting = False


                ' Dim htmlpath As String = "D:\Print-code\test3.html"
                Dim source As String = response.Content ' File.ReadAllText(htmlpath)
                doc.LoadFromHTML(source, True, pgSt, htmlLayoutFormat)

                doc.PrintSettings.PrintController = New StandardPrintController()
                doc.PrintSettings.PrinterName = printer
                'doc.PrintSettings.Copies = 2
                'Print all pages with default printer
                doc.Print()

查看设置为生成目标x86或x64的项目，然后使用相同的Microsoft.mshtml.dll内部版本添加引用

如何了解您的项目设置生成目标右键单击项目->选择属性->选择选项卡build ->查看平台目标

从html转换为pdf时，Spire.pdf组件依赖于Microsoft Internet Explorer。因此，IE必须安装在客户端的计算机上。下面是Spire.pdf支持论坛的链接。你可以在那里找到更多信息。
