Created with a trial version of Syncfusion Essential PDF

Hi,

I've been using the community license, for a lifetime now, being a single developer.

I updated my project to version 20.1.0.47 and in the pdf generated by the program, I found this writing "Created with a trial version of Syncfusion Essential PDF" in the document.

I also generated a new license key by updating it in Global.asax

How do I solve, since in the previous version this did not happen? Am I forced to stop updating my applications or switch to a competing product?

Hi Pio Luca,


Starting with 2022 Volume 1 v20.1.0.47, we are enforcing all Syncfusion customers (evaluators and paid customers) who use Syncfusion installers or NuGet packages from nuget.org must generate and register the corresponding platform and version license key in your projects.


https://www.syncfusion.com/blogs/post/syncfusion-essential-studio-2022-volume-1-is-here.aspx/


Our license keys are version and platform-specific. So, please ensure that all the referenced Syncfusion assemblies\NuGet packages are on the same version as license key’s version.


After upgraded both license key and assemblies\NuGet packages to the same version, could you please try cleaning your project, nuget cache, deleting the bin\obj folders and rebuild your application, then check whether it resolves the issue?


Please follow the below knowledge base article to resolve the license warning message.


https://www.syncfusion.com/kb/12756/how-to-resolve-syncfusion-license-popup-message-or-trial-message-warning


If the reported issue is still not resolved,  please share us the following details to check issue from our side, 

  1. List of Syncfusion nuget packages\assemblies used and its version.
  2. License key registered.
  3. TargetFrameWork and Platform of your application.
  4. Screenshot of the issue and license key registered place.

Hi Jeyaseelan,

thanks for the support.

I have performed all the points indicated in the guide, but I continue to have the same problem.

The watermark appears only on the generated PDF file.

        {

            try

            {

                //Register Syncfusion license

                Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("Mgo+DSMBPh8sVXJ0S0d+XE9AcVRDX3xKf0x/TGpQb19xflBPallYVBYiSV9jS3xTckVkWXZbc3BQR2VUVQ==;ORg4AjUWIQA/Gnt2VVhhQlFaclhJXGFWfVJpTGpQdk5xdV9DaVZUTWY/P1ZhSXxRdkFjXn9XdXdRQ2FaWEA=;NRAiBiAaIQQuGjN/V0Z+XU9EaFtFVmJLYVB3WmpQdldgdVRMZVVbQX9PIiBoS35RdEVnWXheeXFWQmVdVkxy");

Hi Pio Luca,


We cross checked the shared license keys that are valid for JavaScript, ASP.NET MVC and File Formats v20.1.0.47. Could you please ensure that the license key is registered before initiating any Syncfusion controls in your project?


We suspect that still old Syncfusion.Licensing assembly might be used in the application. Could you please try cleaning your project, NuGet cache, deleting the bin\obj folders and rebuild your application, then check whether it resolves the issue?


To know about registering license key,

https://ej2.syncfusion.com/aspnetmvc/documentation/licensing/license-key-registration

Also, you should set “CopyLocal” as True to Syncfusion.Licensing.dll along with all other Syncfusion assemblies and ensure that the Syncfusion.Licensing.dll assembly also present in the application deployed folders.

   
If the reported issue is still not resolved,  please let us know your most convenient time to schedule the web meeting so that we can check and resolve the issue on your machine as early as possible?


Regards,

Jeyaseelan M

As written in the previous post, I have already performed all the operations listed, cleaning the cache, clearing the folders and rebuilding, also the attached image is taken from the bin folder and as you can see the version of the license dll is correct. Moreover, all the components used work well and do not show any watermark, only the generated pdf has this problem.

I believe there is a problem in the license dll, since I updated a different application is also here I had a licensing problem, performing all the steps you indicated and generating the correct key I had this message "The included Syncfusion license (v) is invalid for version 20.1.0.47." in addition to the same problem on the generated pdfs.


I attach an example that shows the problem.

hi,

i am also experiencing the same issue, i have followed the steps you have listed and i still have ' Created with a trial version of Syncfusion Essential PDF' appearing on the output generated PDF. this seems to be a bug rather then a  invalid license. can you please advise

thanks



JM Jeyaseelan M Syncfusion Team April 11, 2022 01:09 PM UTC

Hi Pio Luca,


Sorry for the inconvenience.


We are having a problem with the region date and time format while validating the license. This issue has been resolved now, and it will be included in tomorrow's (April 12, 2022) weekly release.


Could you please change the date’s regional format to English (United States) and confirm the application is working properly without any license errors?




We will notify you soon the latest Syncfusion.Licensing is available in the nuget.org with the fix.


Please let us know if any concerns.


Regards,

Jeyaseelan M

Yes I confirm


JM Jeyaseelan M Syncfusion Team April 12, 2022 12:15 PM UTC

Hi Pio Luca,


Thanks for your patience.


We have published the latest Syncfusion licensing NuGet packages v20.1.0.48 into nuget.org with the fix


Please update the Syncfusion.licensing and all the referred Syncfusion NuGet packages to the latest v20.1.0.48 and confirm us that the problem has been resolved or not.


Let us know if you face any issue.

NW Noel Walsh November 24, 2023 05:55 PM UTC

Hi,


I'm having the same issue with an ASP.Net Web Application.


I'm registering the license in the Global.asax


All my dlls are version 22.1460.34.0 (including Syncfusion.Licensing)


And the license I'm using is the one generated with the link in the red error message I got in the PDF I created with the DLL:


Essential Studio Enterprise Edition 22.1.34


Could you please advise?


Regards


JM Jeyaseelan M Syncfusion Team November 27, 2023 09:20 AM UTC

Hi Noel,


We had an issue with the regional date and time format in v22.1.34 during the license validation process. However, we have successfully resolved this issue, and it has been included in the weekly release v22.1.36.


To ensure that, please install the latest version of Syncfusion.Licensing v22.1.36 from nuget.org and keep the remaining packages in v22.1.34.


If you encounter any problems still, please share the following details.


  1. List of Syncfusion NuGet packages, assemblies or scripts used and its version,
  1. Target Framework and Platform of your application, 
  1. Screenshot of the issue.

Regards,

Jeyaseelan M
