Activation Nitro Pro 12

[Phillip Cannon]

I have Nitro Pro 12 with a version 12 serial number that I'm trying to activate. When I register, it gives a -24 activation error. I've tried the deactivation wizard which tells me I have 0 installed and 2 available. This was originally installed on a Windows 10 machine with a mechanical drive. The new install is on Windows 11 with a SSD. Any advice?

Hello @Phillip Cannon,

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 12?

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.

x64 http://install.nitropdf.com/professional_12169574/en/retail/nitro_pro12_ba_x64.msi
