Activation of Nitro Pro 12 with no active installs

[Jess Thackston]

I have the same issue. I installed Nitro 12 and the license checker says my license is for version 12 and I have 2 installs available. When I try to activate, I get an error stating the license number is invalid.

Hi @Allain Umalin 
Thank you for getting back to me with this information. We have 64 bit systems so I downloaded the x64 msi, but it does not work at all. Nitro does not download and it just makes the system slow until I restart Windows Explorer process. This msi does not seem to be functional.
Thank you,
Jess

Hello @Jess Thackston,

Thank you for your response and patience.

This is the first time we have received such behavior when working with our MSI installers.

Could you please delete the you currently have, download another copy, save it to your Desktop and run the installer there?

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