Hey there,

Similar to this post (https://www.princexml.com/forum/topic/3012/accept-license-from-stdin) I want to pass the license key via the --license-key flag, which is documented here (https://www.princexml.com/doc/command-line/#general-options). For some reason that flag is not working even though I've removed the <signature> node from my license file (placed in the default location) and I'm using the signature value as the flag value (--license-key=SIGNATUREHERE).

If I run "prince --help" I cannot see that flag. Is this expected? I've also tried to find release notes mentioning that the flag has been removed, but I could not find anything.

Am I doing something wrong? Am I missing something?

My license (after removing the <signature> node looks like this:

<license id="some-id">
<name>SOME_NAME</name>
<vendor>YesLogic</vendor>
<product>Prince</product>
<version>15</version>
<end-user>SOME_USER</end-user>
<date>SOME_DATE</date>
<option id="upgrades">SOME_DATE</option>
</license>


I'm using:
Prince 15.4
build-date: 2024-08-13
build-commit: c73c27a7ab9d659eae7e9e183f297d34395b156e
build-compiler: rotd-2024-02-27

I've tested this on Mac (M3 Pro) and a Linux machine (running Ubuntu). The issue is there in both of them.

Thanks in advance!

What is the error you are receiving?

Hi Mike, thanks for the quick response.

Prince says the license is not valid. When a document is generated I'm seeing the PrinceXML watermark in the document. Also, see the output of "prince --version --debug --license-key MYLICENSEKEY"

Would you be able to email me (mikeday@yeslogic.com) the modified license file you are using?

Hey Mike, sure, I'll send you an email. Thanks!

Sorry I see the issue now, the --license-key option requires the signature element to remain in place after the date element, just with its text content removed:

<date>2024-06-01</date>
<signature></signature>

We will need to update the documentation to clarify this.
