Evaluation License error message appears while using Aspose.Words

Aspose.Words Product Family

hi all,

I am not sure where to find support for this. But we bought license sometime in April-2025 and it worked fine, but today we have suddenly started getting the watermarks on the word docs created via aspose. Our license is valid for 1 year and we have confirmed that we are not using the temporary license.

What could be the cause? What is the support email address to send our queries? All I have the sales email address.

It appears you are encountering an issue with the Aspose.Words evaluation license, which is resulting in watermarks on your documents. Here are several potential reasons for this problem:

  1. License Expiration: Although you mentioned that your license is valid for one year, please verify the expiration date. If the license has expired, it will revert to evaluation mode.

  2. License File Location: Ensure that the license file is correctly referenced in your code. If the application cannot locate the license file, it will not be applied.

  3. Multiple Instances: If you are running multiple instances of your application, confirm that all instances are using the same license file.

  4. Code Implementation: Check that the license is being loaded correctly in your code. Here’s a sample code snippet to load the license:

    License license = new License();
license.SetLicense("path/to/your/license/file.lic");

If you have verified that your license is valid and correctly implemented, but the issue persists, I recommend reaching out to Aspose support for further assistance. You can contact them at support@aspose.com for queries related to licensing.

If you have any further questions, feel free to ask!

@vyasanand Please check the following points:

  • Make sure your call to SetLicense gets executed. Step through in the debugger.
  • Make sure your code does not catch an exception thrown by Aspose.Words licensing code. For example, Aspose.Words will throw if it cannot find the license.
  • Make sure the input documents do not already have the evaluation message. Aspose.Words does not delete existing evaluation messages.
  • Make sure SetLicense is executed before you instantiate any Document object.

Thanks Alexey, this was working fine till last week. We have confirmed no code changes after that. We create new documents run time and hence should be just fine.
