When your CP Plus NVR prompts you with a .dmp error or asks you to send a webException file to R&D, it means the Edge browser's active X/plugin engine has crashed. Legacy CP Plus and Dahua OEM systems rely on outdated ActiveX plugins that Windows 11 no longer natively supports without the proper browser adjustments. [1, 2, 3, 4]

1. Enable Internet Explorer (IE) Mode

Since Windows 11 retired the standalone Internet Explorer, you must activate its underlying mode in Microsoft Edge. [1]

1. Open Microsoft Edge.
2. Click the three dots (...) in the top-right corner and go to Settings.
3. Select Default browser from the left-hand menu.
4. Under the Internet Explorer mode settings, change "Allow sites to be reloaded in Internet Explorer mode" to Allow.
5. Add your NVR’s IP Address to the IE Mode page list.
6. Restart the browser and navigate to your NVR. [1, 2, 3]

2. Adjust ActiveX Controls

The .dmp crash is usually triggered by Edge blocking the plugin. Once you have IE mode running, adjust your security settings: [1]

1. Open the Windows Start Menu, search for Internet Options, and open it.
2. Go to the Security tab, click Local Intranet, and then click the Custom level... button.
3. Scroll down to ActiveX controls and plug-ins.
4. Set "Download signed ActiveX controls" to Prompt or Enable.
5. Set "Initialize and script ActiveX controls not marked as safe" to Prompt or Enable.
6. Save the settings, refresh the Edge browser, and download the plugin when prompted. [1]

3. Clear Existing Crash Data

If the browser continues to crash, you need to clear the corrupted cache causing the .dmp logs.

1. Press Win + R on your keyboard, type inetcpl.cpl and hit Enter.
2. Under the General tab in the Browsing History section, click Delete.
3. Check Temporary Internet files and website files and Cookies and website data. Click Delete.
4. Re-open Edge, log in, and click to install the web plugin afresh. [1, 2]

4. Use the Smart PSS Desktop App

If web access remains unstable on Windows 11, the most reliable long-term alternative is to use the dedicated desktop viewing software rather than a web browser.

1. Download the official viewing client (often branded as CP Plus gDMSS or Smart PSS) for PC from the official CP Plus World website.
2. Add your NVR into the software via its IP address or P2P Cloud ID for stable, browser-free viewing and playback. [1, 2]

If you want, let me know:

• Is your NVR currently updated to the latest firmware?
• Are you attempting to access it via the Local IP (e.g., 192.168.x.x) or a Public IP/Domain?
