找不到 ABCChrome、WebSupergoo。ABCpdf11.Internal.PDFException

Question

出于某种原因，我无法弄清楚是什么导致了 ABCpdf 出现此错误。我们正在从 v9 升级到 v11。我们已尝试包含 dll 和一个参考，但似乎都不起作用。

出错的行在docPDF.AddImageHtml(strHTML);

我们正在使用 Webforms 网站和 IIS。

Answer 1

要解决此问题，我所做的是卸载 ABCPDF 以进行自动安装。从 bin 文件夹中删除了所有 DLL。然后我按照找到的说明手动安装了 DLL here.

然后 ABC PDF 开始正常工作。似乎 ABC PDF .net 的自动安装导致手动安装出现问题。

Answer 2

我收到错误 Unable to start ABCChrome engine。

在我的例子中，ABCPdf was added via nuget package manager，而不是直接安装在目标服务器上。

我的解决方案是停止我的服务，进入任务管理器并终止 ABCPdf 进程，然后重新启动我的服务。
