Troubleshoot Windows Sandbox

This article lists some common issues with Windows Sandbox and possible solutions. To submit feedback about Windows Sandbox, see Where can I provide feedback?

Error	Possible Solution
WININET_E_NAME_NOT_RESOLVED WU_E_PT_ENDPOINT_UNREACHABLE	Upgrade to Windows Sandbox app fails because user isn't connected to internet or network adapter is connected but no internet connection. Check your internet connection.
ERROR_FILE_NOT_FOUND	.wsb config file provided by the user doesn't exist. Make sure that the path to the .wsb file is correct.
E_INVALIDARG	The .wsb file provided by the user is invalid or has errors. Check the .wsb file.
REGDB_E_IIDNOTREG	Verify if Windows Sandbox component is enabled under 'Turn Windows features on or off'. For more information, see Install Windows Sandbox
The following settings are enforced by your IT administrator.	.wsb file has a setting enabled that is controlled via group policy.
No hypervisor was found. Please enable hypervisor support.	Windows Sandbox only supports Hyper-V Hypervisor. Third-party hypervisors are not supported. Ensure that Hyper-V is enabled.
Cannot upgrade to the latest version of Windows Sandbox	Ensure that your device has access to the Internet, Windows Update and Microsoft Store. Beginning with Windows 11, version 24H2, the old Windows Sandbox app attempts to download the latest version from the Store. If the upgrade fails initially, installation continues in the background while the user can still use the app. Additionally, the app is queued in the "Updates & downloads" section of the Microsoft Store app for users who wish to install it manually.
E_FAIL, or E_UNEXPECTED or general failure during installation.	Possible causes: - Installing Windows Sandbox is disabled via group policy. Check with your IT Admin. - Timeout error where we can't reach the Microsoft Store. Try again later.
