Issue with Aspose PDF



I am getting the error.

Error : Could not load file or assembly 'Aspose.Pdf, 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)

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)



Dear Protik,

Please rebuild your project when updated the component.


Thanks for the email. After rebuilding we get

Error : The license is for a different product or corrupted.

However, we are able to use the Aspose with the evaluation license.

1) Please let me know if you let us know why we are getting this error.

2) Could we send Aspose support a copy of the licence file so that they could verify that we have the correct licence file.



You are using a very old version and we have changed the license mechanism. Please contact the sales department to get a new license. If you still can't make it work, please send the license to me via email and let me test it.


Please provide me your email address. I will provide you with both the licence file and the dll we are using.



Dear Protik,

Please send your mail to The dll is not needed.
