Sandbox Error 0x80072746

Common issues

• If you get a "Terminal Services" error message, have you tried the troubleshooting steps from the main instructions?

• If you get a "the setup configuration provider is not registered" error message, have you installed the "Visual Studio C++ Tools"?

• You have tried rebuilding from scratch (Reset your build with ./build.ps1 -Clean, and it will reset your workspace and build.).

Issue

So when I run on my windows 10 the sandbox works fine but when I click on the lockdown browser I added to the runtime directory it shows the loading screen then exits, I manually installed the latest version of lockdown and put it in the c drive and ran it once and it worked upon running it again it says the application can not be ran on a vm. And on my windows 11 when I run sandbox it shows loading screen for 10 seconds exits but still running in background the after 10 minutes I get error (0x80072746)
Update on my windows 10 pro I added the latest lockdown browser setup in the required folder and rebuilt it, initially I was always copying the lockdown.exe with DLL file from my laptop but when I tried running on sandbox it never worked I guess I required the lockdown browser setup.exe, on my windows 11 still no fix to my sandbox not running in the meantime I would create a windows 11 pro vm on VMware.

Expected Behavior

I expected that the Lockdown Browser wouldn't detect that it's running inside a virtual machine.

Also when making use of lockdown browser with responses monitor on sandbox does it capture your windows screen or only what is showing on the sandbox.
No response

(In the future, there's no need to open multiple issues; it's much easier to keep the discussions all in a single place)

I manually installed the latest version of lockdown and put it in the c drive

What do you mean by “manually installed”?

and ran it once and it worked upon running it again it says the application can not be ran on a vm

Either the Lockdown Browser is updating between runs to a version that no longer works, or when you open it the second time, you're launching it incorrectly (but it should be mostly impossible to launch it incorrectly after all of the improvements that @Voidless7125 added).

And on my windows 11 when I run sandbox it shows loading screen for 10 seconds exits but still running in background the after 10 minutes I get error (0x80072746)

In #166, you said

first off my laptop is windows 11 home initially but not windows 11 pro as i patched it with hwid i installed the sandbox from the features menu

and Googling for 0x80072746 suggests that that might be the issue:

• https://old.reddit.com/r/Windows10/comments/cb7qzw/windows_sandbox_for_win10_home_edition_error_code/

• https://superuser.com/questions/1548379/running-sandbox-on-window-10-home-error-0x80072746-the-connection-to-sandbox

You could also try running these commands in an Administrator PowerShell terminal

sfc /scannow
dism /online /cleanup-image /restorehealth
sfc /scannow

and then try launching the Sandbox again, although I'm doubtful that that will work.
