License error on saving in PDF, return to evaluation...

[jcq]

Dear,

Using Spire.doc in C#, WPF app, when saving a doc file to PDF, it works fine on first call, then on second call a warning evaluation message in red is present on every page. It has been working fine for the last 4 years!
My license is valid (to April 2025), i tried to load the license with all methods (implicit and explicit), always same result, after 1st call an evaluation message is printed.
The methods used since many years:
- On app load i init the license:
Spire.Doc.License.LicenseProvider.SetLicenseFileName("license.doc.elic.xml");
Spire.Doc.License.LicenseProvider.LoadLicense();

Then i tried with your latest recommandation, to
using (Spire.Doc.Document _WordPdf = new Spire.Doc.Document())
{
Spire.Doc.License.LicenseProvider.SetLicenseKey("My license KEY");
Spire.Doc.License.LicenseProvider.LoadLicense();
My code here...
{

Without success, also trie to set license before the USING...

Regards
jc

Hi,

Thanks for your inquiry.

The license type you have purchased is Developer Small Business. Please note that the Developer Small Business license allows 1 developer and 1 deployment location (identified by a unique machine ID/MAC address) to use it. When the license is used on machines beyond this limit, it will not be effective, the output file will have the warning messages. Our system has detected that your usage exceeds the limitations of this license. To resolve this issue, please contact our sales team at [email protected].

Sincerely,
