[SOLVED] Viber program stopped working log file: start timer Timers can only be used with threads started with QThread 1

Viber program stopped working log file: start timer Timers can only be used with threads started with QThread 1

I was using VIBER application(cousin of SKYPE) when it stopped working. I re-start my PC (it's installed only on my PC win7-kaspersky) but it doesn't work anymore. The shortcut points to C:\Users\pardis\AppData\Local\Viber where i have:

launcher.db
Viber.exe
Viber.exe.log
ViberUpdater.log
ViberUpdater.cmd
a lot of Qt*.dll files when i click on viber.exe nothing happens(the program doesn't open-nor it's process) but just Viber.exe.log is updated with this message:

1|<> :0 => QObject::startTimer: Timers can only be used with threads started with QThread

Any idea what should i do to make it work again? thanks

Solution

Find Viber's installation folder (C:\Users\<username>\AppData\Local\Viber on Windows 8), navigate to the folder with the name of the latest downloaded version (5.1.1.15 in my case), and run ViberSetup.exe. This should update it to the latest version, keeping your data and resolving the issue.
