Recommended Posts

I tried to open Nitro Pro 10 this morning and the screen that comes up is to activate now or start a free trial.  I used Nitro Pro 10 & it worked last week

Hello @Becky3771,

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

Did your machine just installed Windows updates?

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

It may have. I have not seen any updates but it may have updated automatically

Now the Nitro Pro 10 screen opens up but it says trial mode. When I try to enter my Nitro Pro 10 serial number, it says my license number is already used

Hello @Becky3771,

Thanks for your response and patience.

Upon upgrade of the operating system or installing a major Microsoft update, the Computer ID is changed, as it is comprised partially by the operating system. Once changed, this will no longer recognize the original installation causing the program to revert to trial mode.

To fix this issue, I just made an adjustment on your license, so you can now activate your copy of Nitro Pro by going to Help tab > About Nitro Pro > Activate, entering your serial number and clicking Activate.

Thanks for choosing Nitro Pro and I hope this helps!
