This is a common error that may occure while you are using ABCPDF to generate PDF in asp.net. If you install the component on your machine and use that in application it works fine. However when you copy that application on a machine on which component is not installed, it throws eception as "Unable to load DLL 'ABCpdfCE6.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)".
Solution to this issue is mentioned below.
1. Check that you have properly added the reference of "ABCpdf.DLL" in your application.
2. Copy "ABCpdfCE6.dll" in your bin folder. You can found this dll at "C:\Program Files\WebSupergoo\ABCpdf6 .NET\Common\" on machine where you had install the component.
Happy Programming !!
