Before attempting to install Burp's CA certificate, make sure that you have successfully confirmed that the proxy listener is active and have configured your browser to work with Burp

To install Burp's CA certificate in Internet Explorer, proceed as follows:

With Burp running, visit http://burpsuite in Internet Explorer. You should be taken to relatively plain web page containing a link to download the CA certificate. If not, please refer to the proxy troubleshooting page. Depending on what went wrong, you may be taken there automatically.

Click "CA Certificate" to download your unique Burp CA certificate. Take note of where you save this.

Open the downloaded file. The "Certificate" dialog will open. Click "Install Certificate". In the "Certificate Import Wizard" dialog, click "Next". Select "Place all certificates in the following store" and click "Browse".

In the "Select Certificate Store" dialog, select "Trusted Root Certification Authorities" and click "OK".

Click "Next" and then "Finish". Close all dialogs and restart Internet Explorer. With Burp still running, try and browse to any HTTPS URL. If everything has worked, you should now be able to browse to the page without any security warnings.
