You’re getting this error because Internet Explorer is no longer supported or installable on Windows 11, even via DISM.

===== - Internet Explorer (IE) was permanently retired by Microsoft. =====
* On Windows 11 (especially 22H2, 23H2, and 24H2), the IE capability package no longer exists in the OS image.
* When you run: ``<code> DISM /Online /Add-Capability /CapabilityName:Browser.InternetExplorer[[User:Lukegao|Lukegao]] ([[User talk:Lukegao|talk]]) 05:35, 18 December 2025 (UTC)0.0.11.0 </code>`<code> DISM looks for a component that has been removed from Windows, so it fails with: </code>`<code> Error: 0x8000ffff (Catastrophic failure) </code>``

# Set “Allow sites to be reloaded in Internet Explorer mode” → Allow
# Restart Edge
# Open a site → Settings → Reload in Internet Explorer mode

This uses the IE engine (MSHTML) without the old browser.

===== Your only options are: =====
* 🖥️ Windows 10 (older builds)
* 💿 Virtual Machine with Windows 10 or Windows 7
* 🏢 Enterprise LTSC (older versions only)

Windows 11 will not support IE under any circumstances.

===== - On Windows 10 ≤ 21H2, IE was still a removable capability =====
* On Windows 11, Microsoft: - Removed the package - Blocked reinstallation - Redirected all IE calls to Edge

Your system is fine — the command is just obsolete.

If you want, tell me why you need IE (legacy site, ActiveX, old app, testing, etc.), and I’ll give you the best working solution for that exact use case.
