Hello @hkhangura,

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

I just made an adjustment on your license so please try upgrading again to Nitro Pro 13 with a discounted rate.

Thank you for choosing Nitro and I hope this helps!

Could not activate either after you reset my license. I cannot use my account at all! I need to have a working account and do not want to upgrade something that isnt working. What next!

I also received this error for one of our eight Nitro Pro 9 licenses.  The first seven upgraded without issue.

My account has reverted back to trial mode, after deactivating account it now says my serial code does not exist. I purchased Nitro version 12.

Hello @hkhangura,

Thank you for your private message.

To further assist you, please refer to these steps:

1. 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.

2. Clear the content of the directory under C:\users\your_username\Appdata\local\temp. For whatever reason, not all temp files automatically remove themselves and is NOT usually caused by Nitro Pro files. Kindly note Appdata folder is hidden and to unhide it, please refer to this article  https://cybertext.wordpress.com/2012/05/29/cant-see-the-appdata-folder/

3. Download and install Nitro Pro 13.9 using below offline installers:

x64 http://install.nitropdf.com/professional_1391155/en/retail/nitro_pro13_ba_x64.msi

If you are not sure which to pick, this will help: https://kb.gonitro.com/knowledgebase#/search/64/000003790 

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

Thank you for choosing Nitro and I hope this helps!

Hello @mnice,

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

Since I am unable to pull-up your account, 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.

Thanks and I am looking forward to hearing back from you.

Hello @mnice,

Thank you for the private message.

Please be informed that 'The serial number entered does not exist' 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

If you are unsure if your machine is using 32 or 64-bit, please refer to this link: https://kb.gonitro.com/knowledgebase/#/search/64/000003790 

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

Thank you for choosing Nitro and I hope this helps!
