Marilyn Reynolds 0 Report post Posted January 22, 2020 (edited) I purchased Nitro Productivity Suite in March 2019, Serial # ****. Yesterday, Jan 21, when I looked on Nitro, it said I had two activations and one deactivation. That I could deactivate, and then activate. I clicked the Deactivate button. I have not been able to activate Nitro onto my new laptop. I received an Error 401. I have not loaded this program onto any other device. I need some HELP! I sent a message yesterday, but guess I didn't get a reply, never saw it. My Order Reference Number ****; my cell is ****. Please help! Edited January 22, 2020 by Leslie V.

Leslie V. 0 Report post Posted January 22, 2020 Hello @Marilyn Reynolds Thanks for reaching out to us! Please uninstall Nitro Pro and install Nitro Pro 12. You can get the correct version 12 installers from this page: https://www.gonitro.com/nps/product-details/downloads After installation, you can activate by opening Nitro, click on the Help tab > About Nitro Pro > Activate and enter your serial. Please let me know how that goes. Share this post Link to post Share on other sites
