Steven_L 0 Report post Posted September 27, 2019 Hello, I installed Nitro-Pro 12 on a new Windows 10 Computer. Unfortunately I can't get it activated. At the activation window I have to download a Activation-Certificate, but when I insert the Installation-ID on the Website, it says that the Installation-ID is invalid. What can I do to activate the Software? Share this post Link to post Share on other sites
