Could not load file or assembly 'bin\ABCpdf8-64.dll' or one of its dependencies. The module was expected to contain an assembly manifest.
Please find below full details from FusionLog Viewer

ABCpdf8-64.dll is NOT a .NET assembly. It is a native DLL, which will be called by ABCpdf.DLL, which is the .NET assembly.
This error message suggests to me that you tried to reference ABCpdf8-64.dll as a .NET assembly, perhaps from your web.config file. You should instead reference ABCpdf.dll.
