Could not find ABCChrome, WebSupergoo.ABCpdf11.Internal.PDFException

For some reason I can't figure out what is causing this error with ABCpdf. We are upgrading from v9 to v11. We have tried including the dlls and just a reference but neither appear to be working.

The line that the error occurs is on docPDF.AddImageHtml(strHTML);

We are using a Webforms website and IIS.

An exception occurred: WebSupergoo.ABCpdf11.Internal.PDFException: Could not find ABCChrome.

To fix this issue what I did was uninstalled ABCPDF for Automatic installation. Removed all DLLs from the bin folder. Then I manually installed the DLLs following the instructions found here.

Then ABC PDF started working as normal. Appeared as though an automatic installation of the ABC PDF .net was causing issues with manual installation.
