It's possible to extend demo evaluation period?

Hi, i would like to try pdfSdk again but my demo installation is very old. How can i extend demo evaluation period?

Thanks

Thank you for your interest in PDFNet.

The only way to “extend” the trial period, is to continue your evaluation on another computer, or even run on a virtual machine (VM).

Note that there will be watermarking while you are running in trial mode.
