I am trying to run the Patagames.pdf.dll library in a web service under IIS, but I keep on getting the PDFium.dll not found error.

It runs on my PC perfectly - but when I publish it, it won't run on the web server.

I have carefully checked the security properties on PDFium.dll to ensure it is executable by the application pool ID (and tried giving all users full access).

I have tried the following code to direct the server precisely to the DLL, and it's giving the correct location:

Code:
                string codeBase = System.Reflection.Assembly.GetExecutingAssembly().CodeBase;
                UriBuilder uri = new UriBuilder(codeBase);
                path = Uri.UnescapeDataString(uri.Path);
                string base_path = Path.GetDirectoryName(path);
                base_path = Path.GetFullPath(Path.Combine(base_path, @"..\"));
                path = Path.Combine(base_path, @"pdfium.dll");
                PdfCommon.Initialize(null, path);


Any suggestions please?

Also make sure that used pdfium.dll has a bitness same as application pool (64/32 bit).

Thanks - it was the "bitness" of the application pool. :)

Working now.
