Unable to upgrade

[Janice Wiebelhaus]

My Nitro Pro won't open, so I am trying to upgrade to see if that is the issue, but when I enter my serial number it says it  can't be verified.

Hello @Janice Wiebelhaus,

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

Does the program stay in the Taskbar? if yes, this is a common scenario when multiple monitors are being used. When Nitro Pro is opened on a monitor that is later disconnected, it won't default to a current "active" display which causes Nitro Pro to display on the missing monitor. Kindly try these steps:

1. Try rebooting your machine.

2. If not fixed after rebooting, right-click Nitro Pro's desktop shortcut > Properties > Shortcut tab, under Run, select 'Maximized' and hit the OK button.

3. If setting to 'Maximized' did not help, focus on Nitro Pro and perform the following:

a. Click on it on the Taskbar > Press the Windows key + Left/Right arrow until Nitro Pro appears. What was the result?

b. Right-click on it then select Move. Did it help?

c. Open Task Manager, expand Nitro Pro then right-click 'Nitro Pro' > select 'Bring to front'. How did it go?

If the above steps did not help, please provide more details/information about the behavior of the program in your next response.

 

Thank you for choosing Nitro and I hope this helps.
