Greetings @Hossameldein Negm

Thank you for reaching out through our Community Forums!

Based on the screenshot, I can see that you were able to launch the software but it only sits in Windows' Taskbar with no error message.
Please try the following and see if it helps:

1. Open Nitro PDF Pro again. 
2. From the Windows Taskbar, focus on Nitro Pro by clicking on it.
3. Press the Windows key + Left/Right arrow on your keyboard until the Nitro Pro window appears.

Sometimes this happens when Nitro Pro is stuck outside the displayed area on your monitor. 
You can also check if you can move the Nitro Pro window (in case it's off-screen) by holding Shift and right-clicking the Nitro Pro icon in the Taskbar and selecting, "Move". Then, continuously press the Left/Right arrow key on your keyboard until it appears on the screen.

You may also try Maximizing the application in the Task Manager > Processes tab. When you see the Nitro Pro icon under the Processes tab of Task Manager, expand it then right-click and select Maximize. 

Once the software is up, you can proceed with the activation. To activate, navigate to the Help tab > About Nitro Pro > Activate, enter the serial number then click Activate. 

Kind regards,
