Nitro PDF Pro 8 on Windows 10 Pro Keeps Requiring Activation After PC Reboots

[jm2019 0]

I successfully activated Nitro PDF Pro 8 on my Windows 10 Pro PC, but after I reboot the PC and open Nitro PDF Pro 8 it asks for Activation again.  I tried uninstalling, rebooting and then re-installing, but the problem persists.  Please help.

Hello @jm2019,

Please try the following workaround:

- Close Nitro Pro
- Go to C:\ProgramData\Nitro\Pro 8 (note that ProgramData is a hidden folder)
- Delete the Nalpeiron folder
- Open Nitro again
- Activate it

Please let me know how it goes.

Hi Leslie. Thank you for the reply.

I went to the C:\ProgramData\Nitro, but no Pro 8 folder exists.  All that is there is a folder labeled "Pro" and inside that folder there is no Nalpeiron folder.

Hello @jm2019,

Unfortunately, it is one of our oldest versions of Nitro Pro which we no longer provide support for. To read more about our sunset policy, please go here: https://www.gonitro.com/nps/product-details/sunset-policy

We recommend that you try Nitro Pro 13.
You can run it in trial mode for 14 days!
After that, it can still be used as a PDF reader.
