Windows Vivaldi start issue

cprice2437

Vivaldi no longer runs on my PC. I have Windows 11 version 23H2 on AMD Ryzen 5 powered 2023 build and 32GB of RAM.

Vivaldi has been my preferred browser for several years and until the other day was running fine. I have added no additional software - ironically I also have Firefox loaded on my PC and this has also failed to load in exactly the same way.

I have run through the steps identified in this forum (most of which assume you can actually open Vivaldi) and tried to run as an administrator - nothing works. I have now uninstalled and re-installed Vivaldi with the same result - no matter how I try to open Vivaldi it just does nothing. I have switched off my firewall and virus protection - no change.

I have downloaded Brave and I am using that which works fine. The issue happened without warning - maybe a Windows update? This was updated on 13th December - 2024-12 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5048685) but I cannot find anyone with these issues as a result of that update.

Has anyone any suggestions - this is troubling me.

Thanks

@cprice2437 Let us check with a log file.

Start cmd.exe
Run command
"%ProgramFiles%\Vivaldi\Application\vivaldi.exe" --enable-logging=stderr --v=1 > "%LOCALAPPDATA%\vivaldi-debuglog.txt" 2>&1

Startup log is C:\Users\YOURUSERNAME\Appdata\Local\vivaldi-debuglog.txt

TbGbe · Win: Snapshot Vivaldi 7.4.3653.3

@cprice2437 As you can't open Vivaldi, you probably won't know the whole version number - but are you trying to run Stable or Snapshot ?

cprice2437

@TbGbe I have the latest stable version

Thanks - I have tried to run this from the cmd line and I get this in the file: .vivladi_reporting_data.

I don't have anything resembling C:\Users\MY USERNAME\Appdata\Local\vivaldi-debuglog.txt

Is this helpful? It feels that the command provided isn't really running when I paste it into the command line editor...

Thanks

@cprice2437 Copy %LOCALAPPDATA%
Paste into Explorer address field
Hit Return

No file vivaldi-debuglog.txt in files list?

@DoctorG

No debug file

@cprice2437 What do you see if you run this in cmd.exe window:
"%ProgramFiles%\Vivaldi\Application\vivaldi.exe"

"%ProgramFiles%\Vivaldi\Application\vivaldi.exe"

I cut and paste this into the Command Prompt dialogue box and I get

DoctorG

@cprice2437 OK, where do you have your Vivaldi installed? Perhaps for user?
Then try in command line:

"%LOCALAPPDATA%\Vivaldi\Application\vivaldi.exe" --enable-logging=stderr --v=1 > "%LOCALAPPDATA%\vivaldi-debuglog.txt" 2>&1

After Vivaldi had ended/exited, you should see the debug file now if you run command:
dir "%LOCALAPPDATA%\vivaldi-debuglog.txt"

You can see it in Explorer if you copy %LOCALAPPDATA% and paste into address field.
