找不到ABCChrome，WebSupergoo.ABCpdf11.Internal.PDFException

Question

由於某些原因，我無法弄清楚是什么導致了ABCpdf的錯誤。 我們正在從v9升級到v11。 我們嘗試包括dll和只是參考，但似乎都沒有用。

發生錯誤的docPDF.AddImageHtml(strHTML);

我們正在使用Webforms網站和IIS。

Answer 1

為了解決此問題，我卸載了ABCPDF以進行自動安裝。 從bin文件夾中刪除了所有DLL。 然后，我按照此處找到的說明手動安裝了DLL 。

然后，ABC PDF開始正常工作。 好像自動安裝ABC PDF .net導致手動安裝出現問題。

Answer 2

我收到錯誤消息Unable to start ABCChrome engine 。

在我的情況下， ABCPdf是通過nuget軟件包管理器添加的 ，而不是直接安裝在目標服務器上。

我的解決方案是停止服務，進入任務管理器並殺死ABCPdf進程，然后重新啟動服務。
