Help deactivating & reactivating serial number

[Henry Newbery]

Hi I have a new laptop and am trying to access Nitro Pro on it but I am having issues. First I downloaded 11 since that was what I was using on my previous laptop. I then got  error message : -24: Activation Error.

When I used the serial number database it said:

Version: 12

Status: Active

Number of Activations: 0

Number of Activations allowed: 2

So I downloaded 12 instead but now I get -22: Wrong Licence Number, due to incorrect version... please help I am not sure how to proceed and which version to download/install.

Greetings @Henry Newbery

Thank you for reaching out to us through our Community Forums!

You should be able to activate if the version and build of your Nitro PDF Pro is 12.16.9.574. You can see this information by going to the Help tab > About Nitro Pro. 
If your installation is not on 12.16.9.574, please download the installer from the link below:

https://www.gonitro.com/product-details/downloads - click the 'Download Nitro Pro 12' link.  

After the installation, you can activate by going to the Help tab > About Nitro Pro > Activate. Enter the serial number then click the Activate button. 

If you are interested to upgrade your license to version 13 (latest version) with a discounted price, please let me know so we could check the eligibility of your license.
The Nitro PDF Pro 13 comes with significant stability and security improvements, as well as many feature enhancements, in particular in conversion and OCR functions.

Kind regards,
