The error message "Open Internet Shortcut Extension DLL" (often appearing as "Internet Shortcut Shell Extension DLL") is a common issue in when a browser fails to hand off a protocol link—like —to a local client application. Microsoft Learn Root Cause
This occurs because the Windows registry doesn't know which program should handle the specific URL protocol used by EVE-NG nodes. Instead of launching a terminal like
, Windows attempts to open it as a generic web shortcut and fails. Microsoft Learn Solutions & Troubleshooting 1. Switch to HTML5 Console (Immediate Fix)
The simplest workaround is to avoid local client tools altogether. : At the EVE-NG login screen, change the Console Type from "Native Console" to "HTML5 Console"
: Nodes will open directly in a new browser tab without needing external software. 2. Install the EVE-NG Client Pack
If you prefer using local tools (SecureCRT, PuTTY, etc.), you must install the integration package. Windows Client Side Pack from the official EVE-NG site : After installation, navigate to the C:\Program Files\EVE-NG folder and run the files (e.g., win7_64bit_putty.reg
or the SecureCRT equivalent) to fix the registry associations. 3. Enable Missing Windows Features
Some users report that missing legacy components prevent the shell extension from working. Settings > Apps > Optional Features > Add a feature Components Internet Explorer (legacy mode) and the OpenSSH Client are installed. : Reboot your PC after adding these features. 4. Fix Permissions (Server Side)
If the nodes fail to start or connect regardless of the browser, ensure the server permissions are correct.
C:\Program Files\EVE-NG\eve_ng_shortcut.dll (or eve_ng_url.dll).If the .url key is missing entirely:
HKEY_CLASSES_ROOT → New → Key → name it .url .(Default) = urlfile.shell\open\command.The DLL works in conjunction with a browser extension. Inside the guest Windows VM:
https://<your_eve_ng_server_ip> (use HTTP if no SSL).Instead of relying on browser downloads, use the EVE-NG desktop client. Right-click any node → Open → Native Console. This uses a persistent connection via the eve:// protocol.
A Windows shell extension DLL can provide a convenient "Open Internet" shortcut for EVE-NG node management IPs, but it requires careful implementation of COM, registry registration, input validation, and installer support. For many users a small PowerShell/AutoHotkey or SendTo executable may be a faster, safer alternative. eve-ng open internet shortcut extension dll

The "Open Internet Shortcut Extension DLL" message in EVE-NG typically appears when the Windows operating system is unsure how to handle a telnet://, ssh://, or vnc:// link clicked within a web browser. This occurs because EVE-NG uses these custom URL schemes to trigger local terminal clients (like PuTTY or SecureCRT) to open nodes. Why This Happens
When you click a node in the EVE-NG web interface, the browser passes a command to Windows to "open" a specific address. If the required registry entries or handler applications (defined in shdocvw.dll or url.dll) are missing or misconfigured, Windows prompts with a shell extension error or asks you to "choose an app". How to Fix It
To resolve this and ensure your terminal opens automatically, follow these steps:
The "Internet Shortcut Shell Extension DLL" (ieframe.dll) is a core Windows system component, but in the context of it is often associated with the Windows Client Side Pack integration Overview of EVE-NG Integration
EVE-NG is a web-based network emulator. To open nodes (like Cisco routers) using local applications instead of a web browser, it relies on "handlers" defined in the Windows registry.
: When you click a node in the EVE-NG web interface, it sends a URL protocol (e.g., The DLL Role : Windows uses the Internet Shortcut Shell Extension DLL (ieframe.dll)
to process these shortcuts and hand them off to your local terminal client like PuTTY or SecureCRT. Common Issues & Troubleshooting
Users often encounter errors referring to this DLL when their Client Side Pack is misconfigured or blocked. "Application Not Found" Error : This usually happens if the registry keys for the protocols are missing or pointing to a non-existent path. Browser Security Blocks
: Modern browsers may block the DLL from launching external apps. You must explicitly "Always allow" EVE-NG to open these types of links. Broken Registry Links
: If you uninstalled a terminal client (like PuTTY) and reinstalled it elsewhere, the "Internet Shortcut" extension may still be trying to use the old, broken path. How to Fix EVE-NG Shortcut Errors The error message "Open Internet Shortcut Extension DLL"

The message "Open internet shortcut extension DLL" (or Internet Shortcut Shell Extension DLL) typically appears when EVE-NG tries to open a terminal connection (telnet/SSH) through a web browser but your computer doesn't know which local application to use. This happens because the "Native Console" mode in EVE-NG relies on your operating system to handle specific URL protocols like telnet:// or ssh://. How to Fix the Error
The most common cause is a missing or incomplete installation of the EVE-NG Windows Client Side Pack. Install the EVE-NG Client Pack:
Download the official Windows Client Side Pack from the EVE-NG Download Page.
Run the installer. This will automatically install necessary tools like PuTTY, UltraVNC, and Wireshark, and more importantly, it adds required registry keys to your Windows system. Verify Browser Settings:
If you are using Firefox, it may ask what application to use for a "telnet" link. You must manually select PuTTY (usually located in C:\Program Files\EVE-NG\putty.exe) and check the box to "Always use this application".
Google Chrome may block these pop-ups or fail to trigger the external app if the registry keys from the Client Pack aren't correctly registered. Alternative: Use HTML5 Console:
If you cannot install local tools, you can avoid this error by changing the console type.
On the EVE-NG login screen, change the dropdown menu from "Native Console" to "HTML5 Console". This opens all terminal sessions directly within your browser tabs without needing external software or DLLs. Technical Background Open internet shortcut extension DLL - Microsoft Q&A
This error message, "Open internet shortcut extension DLL," typically occurs on Windows when you try to open a node in the EVE-NG web interface but your computer doesn't know which application should handle the telnet:// or ssh:// link. The Direct Fix Config file (JSON) next to DLL:
To resolve this, you need to install the Windows Client Side Pack provided by EVE-NG. This package includes registry files that tell Windows to use specific terminal clients (like PuTTY or SecureCRT) when you click on a lab node.
Download & Install: You can find the integration package in the EVE-NG Professional Cookbook or on the official EVE-NG website.
Alternative Manual Fix: Users on Reddit suggest downloading SuperPuTTY, copying its files (including the .dll) to C:\Program Files\EVE-NG, and ensuring the executable is named putty.exe. Why This Happens
The "Open Internet Shortcut Extension DLL" is not a standard feature of EVE-NG, but rather a Windows-based system component that users often encounter as a confusing error message or prompt when trying to access lab nodes using the Native Console. The Context of the "DLL" in EVE-NG
In EVE-NG, users have two primary ways to interact with their virtual lab equipment: the HTML5 Console (which runs directly in the browser) and the Native Console. When you select the Native Console, the web browser attempts to hand off the connection to a local application on your computer, such as PuTTY, SecureCRT, or Wireshark.
The mention of the Internet Shortcut Shell Extension DLL (or similar phrasing) typically occurs in one of two scenarios:
Missing Client Tools: If the required EVE-NG Client Side Pack (which includes registry fixes and necessary wrappers) has not been installed, Windows may not know which application to use for "telnet://" or "ssh://" links.
Protocol Association Errors: When Windows fails to find a registered handler for the shortcut link generated by the EVE-NG web interface, it may trigger a system dialogue referencing the standard DLL responsible for handling internet shortcuts, leading to the "Open with..." prompt. Solving the "Shortcut" Prompt
If you are seeing this prompt while trying to open a console to a router or switch in your lab, it indicates a breakdown in how your operating system handles external protocol requests from your browser.
Install the Client Pack: The most effective fix is downloading and installing the Windows Client Side Pack from the official EVE-NG download page. This package automatically registers the correct handlers in the Windows Registry so that clicking a node opens your preferred terminal emulator.
Switch to HTML5: For a "clientless" experience that bypasses local DLL or registry issues entirely, you can select the HTML5 console option at the EVE-NG login screen. This renders the console directly in your browser tab, requiring no local software beyond the browser itself.
Windows Features: Some users have found that ensuring Internet Explorer and OpenSSH Client are enabled under "Optional Features" in Windows Settings can resolve underlying shell extension conflicts.
In essence, the "open internet shortcut extension dll" is a symptom of an unconfigured local environment. By properly setting up the local management tools, you transition from a system error to a seamless, professional-grade network emulation workflow.
Here is the definitive guide to eliminating the DLL error and restoring seamless link opening from your EVE-NG lab.
