Spire PDF license is not applied.

[gofhasd1]

Hello,
We are HUMAX IT Co., Ltd. from South Korea.

We purchased your Spire PDF product today and attempted to apply the license.

However, testing revealed an “Evaluation Warning” displayed at the top of the document.

The start and end dates of the license we received are as follows:
<LicensedDate>2025-09-25T00:00:00Z</LicensedDate>
<ExpiredDate>2026-09-25T00:00:00Z</ExpiredDate>

We are already using your Spire DOC. Could applying the license file as shown below cause any issues?

public class HelloWorldApplication {
public static void main(String[] args) {
com.spire.pdf.license.LicenseProvider.setLicenseKey(“lib/license.elic.xml”);
com.spire.pdf.license.LicenseProvider.setLicenseKey(“lib/license.elic_1.xml”);
.....

Additionally, The current time of the attempt is 19:47 on September 25, 2025, KST.

Thank you.

Hello,

Thank you for your inquiry.
The error is because you used wrong license key. There are two methods to apply the spire.pdf.license.
Method 1:
You can specify the path to your license file as follows:

Code: Select all

com.spire.pdf.license.LicenseProvider.setLicense(path+"license.elic.xml");

Method 2:
You can extract the license key value from the XML file (see the attached screenshot for its location) and apply it directly:

Code: Select all

  com.spire.pdf.license.LicenseProvider.setLicenseKey("your_license_key");

Hello

Even when applying it the way you described, the same Evaluation Warning appears.
Is there another way to check? We need to resolve this quickly.

Thank you.

Hello,

Thank you for your feedback.
Could you please send us a complete screenshot of the "Evaluation warning" in your file along with the version of the Spire products used in your project? Based on the previous screenshots, is there any use of spire.doc in your project?

Hello

Whether or not you register the license key as shown in the attached file, the result displays an Evaluation Warning.

Is there any use of spire.doc in your project?
=> Yes, there is. We convert docx to pdf in some cases, and convert docx to html in others, but Evaluation Warning was not bound to either.

Thank you.

Hello,

Thank you for sharing the details.
When I tested your license using Spire.PDF for Java 11.9.6 in isolation, the resulting file did not contain an evaluation warning. Could you please tell us the specific versions of Spire.PDF and Spire.Doc being used in your project?

[gofhasd1]

Hello

spire.doc = 11.8.1(This license has expired.)
spire.pdf = 11.9.6, 11.8.0, 11.8.3
(All three were tested, and as a result, an Evaluation Warning is displayed at the top of the document.)

Thank you.

Hello,

Thank you for your feedback.
I have successfully reproduced the issue you encountered when using Spire.Doc 11.8.1 alongside Spire.PDF 11.9.6 in the same project. The root cause is that Spire.Doc 11.8.1 was released in August 2023, and in the two years since, we have made numerous adjustments and updates. This has resulted in compatibility issues between the older Spire.Doc version and the newer Spire.PDF version.
Based on my tests, I can confirm that your license functions correctly in a project utilizing the latest versions of both Spire.Doc 13.8.7 and Spire.PDF. Therefore, I recommend updating your Spire.Doc package to the latest version and running your tests again.

Hello

We are currently using Spire Doc version 11.8.1 because it is the last version supported by our current license. Is it acceptable to upgrade as mentioned in the main text? The Spire Doc license has already expired.

We will proceed with upgrading the version and conducting tests as you have checked.

Additionally, Could I also receive the source code that you successfully converted from pdf to docx?

Thank you.

Hello,

Thank you for your feedback.
As your license has expired, you need to renew and update to use the latest version of Spire.Doc. In order to facilitate your test and evaluation, our sales colleagues have sent a 30-day temporary license of Spire.Doc for Java to your email. Please check it in time.
To convert a pdf file to a docx file, please refer to the following tutorial:

Hello,

I have two questions.
First, if I successfully tested using the 30-day license for Spire.Doc, can I use that same license to permanently use Spire.Doc 13.8.7?

Second, when changing the Spire Doc version, we need to verify that existing features function as expected. Could you provide Spire PDF aligned with Spire Doc 11.8.1?

Thank you

Hello,
Thank you for your inquiry.
To continue using Spire.Doc 13.8.7 on a permanent basis, you will need to purchase a new license. We offer discounted renewal rates for existing customers. Additionally, Spire.PDF 9.7.8 is compatible with Spire.Doc 11.8.1, so you may consider using them together. Please don’t hesitate to reach out if you have any questions or need further assistance during testing.
