Hi, we are using your PDF kit product and I would like to check if our license is still active.
Thanks for contacting support.
Technically speaking, there is no Aspose license expiry date. You can use specific Aspose product version released earlier to license expiry date for life time i.e. suppose you have legacy Aspose.Pdf.Kit for .NET license whose expiry date is 10-Oct-2011, so you can continue to use Aspose.Pdf.Kit for .NET 6.0.0 (released on 05-Oct-2011) and all its versions released earlier to that date. However you might not be able to use the same license file with products released after 10-Oct-2011.
You can easily check license expiry date by opening the license file in any text editor and find out ---- tag inside your license file. Please be careful while extracting information from license file because the addition of even a single blank character can make your license file useless.
In the event of any further query, please feel free to contact.
PS, please avoid sharing license file in forum threads.
