Upgrading to Licensed Latest Version of Aspose.Words for .NET API | NuGet vs MSI | Could not Load File or Assembly

Hi Aspose guys,

I had a license of total .net. I used it with Aspose.Words 10.4 well. But today, I tried the latest version of Aspose.Words 11.1, I got this exception:

Could not load file or assembly ‘Aspose.Words, Version=, 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)


Thanks for nay help,

Hi Vuong,

Thanks for your inquiry.

Please first remove Aspose.Words completely from your system. Then remove the reference to old Aspose.Words.dll from your project. Also, delete associated files from your project’s bin folder if present. Then install the latest version of Aspose.Word via msi installer. Add reference to this new DLL in your project and re-build it. Please let us know how it goes on your side.

I hope, this will help.

Best Regards,
