We kept receiving a prompt to register the Advanced PDF Tool.
I have ensured that the license keys for the GUI version and Command Line version are accepted, but it kept asking for us to register when we open the output PDF file.
This happened after we try opening up the GUI version and it was prompting for registration, we put in the key, and it started asking for registration when we open the PDF file.
Please run Advanced PDF Tool with administrator right, input your license key, the Advanced PDF Tool will remember your license key forever.
Please notice, if you don't run Advanced PDF Tool with administrator right, Advanced PDF Tool can't remember your license key, please notice this matter.
