From a long time Opera fan, now exiled to Google Chrome because Opera does not work with
Win 10 Sandboxie.

I have used Chrome in the past as my default browser and only changed to Opera because Chrome dumped support for XP. No support problems now with Windows 10.

Doing exactly the same with Opera ? Failure as usual - white screen.
Goodbye Opera until you sort out your software like Chrome and Firefox have.

From another Sandboxie thread, I see that in addition to --no-sandbox being used, you might have to add OpenIpcPath=*\Sessions\*\BaseNamedObjects\CrSharedMem_* to sandboxie.ini.

To be clear on how to add to sandboxie.ini...

In the Sandboxie control program, select the sandbox in question. Then, click "configure" on the menu bar and choose "Edit Configuration". Then, it'll open Notepad as an administrator and open sandboxie.ini. Add the OpenIpcPath line at the end of the DefaultBox section and save your changes. Then, you can close out of notepad, choose "Configure" again and choose "Reload configuration".

You only need to do all of that though if you can get Opera to work in Sandboxie with the --no-sandbox switch where then Opera crashes sometimes after that. In other words, I wouldn't add that line unless you have do. It makes no noticeable difference for me. Then again, --no-sandbox works for me.

Try disabling McAfee temporarily to see if it's interfering.

Try disabling all extensions in Opera. You can try the --disable-extensions command-line switch to/instead if you want.

Download the Opera installer, launch it, click "options", set "install path" to a folder named "Opera Test" on your desktop, set "install for" to "standalone installation" and install. Once that Opera loads, close it.

Then, open up a command prompt and run the command:

"C:\Program Files\Sandboxie\Start.exe" "C:\Users\YourUserNameHere\Desktop\Opera Test\launcher.exe" --no-sandbox

just to see how things behave with a fresh profile.

I am deeply disappoinjted, but your last fix -
"C:\Program Files\Sandboxie\Start.exe" "C:\Users\YourUserNameHere\AppData\Local\Programs\Opera\launcher.exe" --no-sandbox
never worked - still a white screen.
Gone back to normal Opera opening.

I assume you replaced "YourUserNameHere" with your Windows account username since you said you got a white screen Opera?

In addition to --no-sandbox, try doing this fix.

If that doesn't work, in addition to those, try doing the same command but also add --disable-gpu.

"C:\Program Files\Sandboxie\Start.exe" "C:\Users\YourUserNameHere\AppData\Local\Programs\Opera\launcher.exe" --no-sandbox --disable-gpu

If that doesn't work, click on the start button, type cmd, right-click on the command prompt shortcut and choose "run as administrator". Then try the command again.

Please report back your findings. Thanks.

I sincerely thank you for all your help and effort in trying to get me going with Sandboxie. Very grateful indeed.

Promise -
I will definitely try your latest fix and let you know. It looks very promising.

Never worked

That error dialog says that it can't find launcher.exe. Open up Opera directly, goto the URL chrome://about and look at the Install path under the "Paths" section. That'll tell you what directory launcher.exe is in so you can fix the path for the command. For example, it might be:

"C:\Program Files\Sandboxie\Start.exe" "C:\Users\YourUserNameHere\AppData\Local\Programs\Opera\launcher.exe" --no-sandbox

that you have to do.

Also in the dialog, it shows that you didn't type --no-sandbox correctly.

"C:\Program Files\Sandboxie\Start.exe" "C:\Program Files\Opera\launcher.exe" --no-sandbox
Never worked

Users should not have to fiddle about trying to make Opera work. Why should they when the other browsers give no problem. It is an Opera software matter.

Not disagreeing with you. Just seeing if there's a workaround.

Then why not for me ?

Try this.

Windows Key + r
Type cmd and press enter.

Type the following command and press enter

"C:\Program Files\Sandboxie\Start.exe" "C:\Program Files\Opera\launcher.exe" --no-sandbox

(Adjust path to Opera's launcher.exe to match where your Opera's launcher.exe is at)

Does it work that way?

My computer is brand new, only 3 days old. I have done nothing but elementary learning and basic user operations. I am no novice, having had 14 years of experience, most of that using Sandboxie.
Chrome and Firefox work perfectly with Sandboxie and Opera does not, even with the DIY fixes applied.

--disable-gpu-sandbox helps some, but not all the way, which is why you have to use --no-sandbox.

For Opera, I guess you have to disable the Chromium sandboxing to let Sandboxie's sandboxing do its work.

Not sure why it's not needed for Chrome though.

I also read from that thread that Opera might be a little crashy with --no-sandbox, but I can't confirm that yet.
