The Viber Desktop application is an excellent tool for communication. You can type quickly, communicate with people, and simultaneously be in several Viber groups.
However, in the last several months, many users had problems with Windows 10 and 11. If your Viber does not work on Windows 10, or Windows 11, in this article, I will show you the solution how to fix Viber when it does not respond.
Problem – Viber opens and closes immediately
My problem with the Viber desktop was frustrating. Several times I installed the Viber desktop app, and I had a problem every time because Viber couldn’t not open in Windows even after a new installation. Sometimes, Viber can open after installation, but Viber opens and closes the next day immediately. So how to fix the problem?
How to fix the problem when Viber doesn’t open in Windows?
Suppose your Viber won’t open on the desktop. In that case, the problem is in the Windows registry files because Viber is running but not opening because of a low-level settings glitch in the Microsoft Windows operating system.
To solve the problem, you need to do the following steps:
- Run the Desktop Viber app as Administrator (right mouse click and choose the “Run as administrator” option).
- Viber opens and closes immediately. Problem exists.
- Press CTRL-ALT-Delete, choose Task Manager and check if the Viber process exists. If a process exists, that means Viber is running but not opening.
- Close the Viber process in Task manager (right mouse click and press “End Task”).
- Go to Control Panel\Programs\Programs and Features and Uninstall the Viber application from Desktop Computer.
- In the search box on the taskbar, type Regedit, then select “Registry Editor” (Desktop app) from the results.
- Go to the Edit menu and choose Find (or CTRL F).
- Type Viber and press the “Find next” button.
- Delete each key, value, and data one by one.
- Press F3 to find the following key, value, or data and delete it.
- The job is done when you search in Registry Editor and do not find any Viber-related key or data.
- Install the new Viber Dekstop application.

Disable Firewall for the Viber app
Verify that Viber starts up and shuts down instantly on your Windows 10 device. Your firewall may be blocking the program if the problem has stopped occurring. You should turn on the firewall and configure it to your needs.

Clicking the right mouse button on the antivirus program’s tray icon will bring up a menu where you can switch off the program. Alternatively, you may enter the app’s main window and find a toggle or deactivate option.
