Watermark Appears on Documents Despite Updated License"

[ciocomillas]

We have a desktop app that connects to a web service on an IIS Windows 2022 server.

It was working fine, but since we renewed the license, all documents are generated with a watermark. We are using the 'Developer Small Business' license. When we try to debug the license on the developer's machine, it works without any problem, so we suspect the issue is with the app and web service. Any help would be appreciated.

Hi,

Thanks for your inquiry.
Since the version 11.5.6 of Spire.Doc, we have implemented optimizations and adjustments to the application licensing mechanism, which involve changes to the namespace. Please ensure that you are applying the licensing method detailed below in your usage.

Code: Select all

Spire.Doc.License.LicenseProvider.SetLicenseKey("your license key");

Additionally, it is essential to clarify whether the watermark issue appears only within projects deployed to an IIS environment. Kindly also verify if the watermark occurs when running the project on the local Windows Server 2022 environment, and kindly provide us with your feedback on this matter.

Sincerely,
Nina

Hi,

Thanks for your feedback.
I tested your license with the latest Spire.Doc 12.3.12, but didn't find any issue, your license worked well to remove the red watermark. Could you please provide your sample application that can reproduce your issue to help us do an accurate investigation? Please also tell us the information of your development machine, such as Windows server 2022. You could send your application to us via email ([email protected])
