Nitro 10 Pro Error 23 - License already in use

Recommended Posts


Hi everyone,

I'm trying to activate Nitro 10 in one computer, and isn´t possible because is already in use (Error 23).

For testing, i've installed on other computer and all went well. On both computers installed first time, and both have the same image (Win 10 1803).

I've check and there's no license to deactivate, and already used the clean tools without sucess.

Can you help resolve this problem?

Thank You!

Hello @PDH,

Thanks for posting on our community forums!

With the release of Nitro Pro 12, please be informed that we no longer support the version (Nitro Pro 10 and below) of your Nitro Pro as per our Sunset Policy: https://www.gonitro.com/support/sunset-policy that is why we highly recommend you to upgrade to Nitro Pro 12 from our website https://www.gonitro.com/pricing

If you would like to trial our latest product, Nitro Pro 12, you can download it from here: https://www.gonitro.com/pro/try

It will run as a full featured product for 14 days! After that, if you choose not to purchase it, you can still use it as a PDF reader. You can learn all about some of the features here: https://www.gonitro.com/resources/videos

Alternatively, if you prefer to keep using Nitro Pro 10, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate.
