Thanks for contacting support.
Please note that as a normal rule of practice, the download section do not contain versions older than one year and all the API versions older than one year are automatically removed. I am afraid you might not be able to download API versions from previous years (2010 - 2012). As we maintain a single code-base, so we recommend you to please try upgrading to latest release of Aspose.Pdf for .NET 11.0.0
as it contains new enhancements and fixes for issues reported in older release versions. Should you have any further query, please feel free to contact.
We are sorry for your inconvenience.
