I am getting the error.
Error : Could not load file or assembly 'Aspose.Pdf, Version=184.108.40.206, Culture=neutral, PublicKeyToken=716fcc553a201e56' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
We had a earlier version of Aspose PDF (without the licence file). We upgraded to the recent version and also provided a licence file (purchased today)
