Activation on new computer

[Robert Bye]

Hello,

We're having issues reactivating our Nitro 12 license on a new PC. After entering the license number on the new PC, Nitro keeps coming back with an error (License number already in use). We've also checked on the portal/Find License page and it says the license still has 2 activations available. We do have Nitro still on another old computer that we don't need it on anymore so even though it says we have 2 activations available, we tried to Deactivate it on that other old computer and when we do so, it gives us an error (-20: Error - Invalid License Number)...except it is the same serial number we used on your Find License page and we know it is correct & active. Please help?

Thanks!

Bob

Hello @Robert Bye,

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

Please be informed that '-20: Error - Invalid License Number' means the serial number you are trying to activate is for a different version of Nitro Pro. Looks like we need to uninstall the current version of Nitro Pro on your computer and install Nitro Pro 12. We then activate it using your serial number. Kindly follow these steps:
 
1. Uninstall Nitro Pro from your computer by going to Control Panel > Programs > Programs and Features then reboot the machine.

2. Please clear all your downloads folder or delete all downloaded Nitro installers. This step is important because we noticed that if you are saving all the installers and you download them in the same folder (like the downloads folder), the EXE can pick up any MSI installer in that folder and you may pick-up one of the older builds instead of the newly downloaded package.

3. Download your Nitro Pro 12 using these offline link/s:

x32 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x86.msi 
x64 http://install.nitropdf.com/professional_12163574/en/retail/nitro_pro12_ba_x64.msi

To know if you have 32-bit or 64-bit, please refer to this article:
https://support.microsoft.com/en-ph/help/15056/windows-32-64-bit-faq 

4. After installation, you can activate by opening Nitro Pro, clicking on the Help tab > About Nitro Pro > Activation and entering your serial number.

Rest assured the activation will work after the adjustments we have executed in our licensing server.

Thank you for choosing Nitro and I hope this helps.

OMG I have had the same issue, I purchased the software in 2011, now moving from one PC to another.  Have deactivated, but cannot reactivated.  Tried the steps above, still thrown back into the loop of insert license number, then given 20 digit serial number.....4 times....Followed steps above, and now back to the support loop.

Please contact me to resolve.

Hello @Valerie Burdett,

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

In order to further assist you, could you please provide the serial number of your Nitro Pro?

To send it via private message, hover your mouse on top of my name 'AllainU' and select 'Message'.

This matters because our business installers are different from the online ones.

Thank you very much in advance and I am looking forward to hearing back from you.
