**Brave Version( check About Brave):**Version 114.1.5.2.130

BRAVE - DOS taskkill error  2023-07-19 202731
BRAVE - Error when try to reinstall 2023-07-19 202958

Additional Information:

No matter which way you look at it, this is an older version. The current Brave is Version 1.56.9 Chromium: 115.0.5790.98

Go to https://brave.com/download/ and install from there. I’m not telling you to remove the existing version of Brave or delete files. It’s just by downloading again it should fix whatever you did to cause the corruption and will update to the newest version.

I did as instructed and it looked like it installed. I can’t see which version I’m on because it still won’t open. See Screen shot attached. When I try to open Brave, I get a dialog that says "Do you want to allow this app to make changes to your device? If I select either yes or no, the desktop view returns without opening Brave.


.

OK, I know. I installed the wrong version. I went back and installed the correct version and got the same results. What next?

@IllinoisNightWalker well then, not quite sure what you’d have going on. One of the “simpler” solutions I wonder about is if you have a firewall or antivirus that might be blocking Brave.

Anything beyond that though, I’ll tag @steeven and @Mattches on to see if they might be able to give some ideas. Hopefully they’ll get to you today. If not, likely won’t be until after Monday as Support typically isn’t active here on the weekends.

I’m running Malwarebytes and Vipre, The same as I was running all the time I used Brave in the past. Nothing has changed, so I’m not sure why it would now stop Brave from running correctly. I look forward to any other ideas you might have.

@IllinoisNightWalker,
If I understand correctly, you’ve now downloaded the latest version of the browser from brave.com but it won’t open when launched.

Can you tell me what happens when you try to launch it at this point? Does nothing happen at all? If you open the Windows task manager, do you see any Brave processes running here?

I would also like to know if you look in MWB or Vipre whether or not you see Brave being blocked here — always worth checking.

When I try to open Brave, I get a dialog that says “Do you want to allow this app to make changes to your device?” If I select either yes or no, the desktop returns without opening Brave.

Looking at the Task Manager, there are no Brave processes running that I can identify.

Vipre has no websites or processes blacked. Nothing quarantined in MWB.

@IllinoisNightWalker,
When that prompt comes up, you should definitely be selecting Yes. One useful test here would be to try downloading the Beta version of the browser and seeing if you get the same behavior there. You can download it here: brave.com/download-beta

I installed the Beta version and now have a new icon (blue icon) to launch Brave and it works. However, I no longer have the passwords and bookmarks from my old version (the red icon). There is no change if I try to launch from there. Is there any possible way to recover my passwords and bookmarks from the old version or are they lost forever?

Thank you, Mattches, for the assistance. I will assume there’s no remedy for my lost bookmarks and passwords.

@IllinoisNightWalker hold that thought. @Mattches may be able to offer more insight later. It’s Friday and now more in the evening. They don’t work on the weekends, so if he doesn’t stop by yet today, he may respond with more help after Monday.

The thing is, just looking at your screenshots you have a bunch ‘crap’ installed that might lock Brave so it doesn’t get uninstalled.

Instead of using taskkill, try using wmic process where name="brave.exe" call terminate

or use powershell Stop-Process command example: Get-Process -Name brave | Stop-Process -Force

Also, in your case, what I would do is try to remove Brave from Program files, if the file is being locked (because the process is active) you could see if some other program is locking it and stopping it from closing. But once you remove C:\Program Files\BraveSoftware\BraveBrowser Brave shouldn’t start, which means you should be able to uninstall it.

If somehow that didn’t work, I would try removing all traces of it from registry, because the updater only sees what it is on the registry, once updater doesn’t see any Brave product, it will uninstall itself.
Also, you could try to remove Brave manually through CMD, all you need to do is go to C:\Program files\BraveSoftware\Brave-Browser\Application\Version number\Installer then you open CMD there and just type setup.exe --uninstall --chrome-sxs --system-level and see what happens.

But If you don’t want to keep with it and just want to use Brave Beta, User Data is the ‘same’ across Brave and works similar across Chromium browsers.
So all you need to do is go to %localappdata%\BraveSoftware\ here you will find Brave-Browser-Beta and Brave-Browser and just removing or renaming Brave-Browser-Beta and then renaming Brave-Browser to Brave-Browser-Beta will give you your passwords and everything back, only some settings will be modified in case of new features but that’s it.

The problem is if you had something installed that was causing Brave to crash.

Did you try restarting the PC and then uninstall Brave? because Brave shouldn’t start unless you tested opening and then it crashed and the processes stayed there.

But in that case you have to see if it is the currect Stable User-Data the problem, in that case you have to remove Brave-Browser-Beta and just copy and paste Brave-Browser to create a backup and rename it to Brave-Browser-Beta, if your browser doesn’t start, well, it has to be something in the LocalState file, like a flag, or Preferences file in Default folder, you can rename the files and try again, you can even do it with the stable version, but since Beta works, it would be good to try it there.

I mean you could easily go to CMD and "C:\Program Files\BraveSoftware\BraveBrowser\Application\brave.exe --user-data-dir="%localappdata%\BraveSoftware\TempFolder\" hit enter and see if the problem is some file in your user data and not the browser itself, because your browser will temporary use a new user data (you have to remove it manually afterwards). then you can just troubleshoot by renaming or deleting files from the normal user data, like preferences, which will reset some settings but not too many.

Also you can start Brave with --disable-extensions --no-experiments and that way you will run the browser with nothing like flags or extensions to see if it was one of those causing issues.

It looks easy to troubleshoot, but like I said, if you want to just use a browser, then you can always copy files from Brave-Browser to Brave-Browser-Beta Default folder, like bookmarks, login data, history, web data, shortcuts, favicons, so you can get most of the important stuff, unless you want to do it the other way, copy and paste the whole folder and rename, and delete files until it works.

While I thank you for your response and suggestions, I also realize that your skill set and experience are a pay grade above mine — maybe several pay grades above. I am just a self-taught computer user who is grateful to be have been able to use a great browser like Brave for so long without having any problems. The technical support team at Brave is amazing and I am lucky to have access to their keen brains.

So I hope some of your examples will save the day and I’ll be able to salvage my passwords and bookmarks, but if not, I’ll find my way and be happy.

Be well, Rita
