Installing an SSL certificate on the IIS5 and 6 is quite easy. The IIS Wizard will guide you through all the important steps required to create a CSR and link to the desired web page.
Please note that it is generally not possible to use the CSR generator in conjunction with the IIS web server as it only accepts certificates for which the CSR was generated on the server itself.
After you have successfully ordered and received your SSL certificate, you can start installing it on the web server.
You can check whether the installation of the certificate has worked as desired by simply calling up the website with https instead of http as usual. The SSL Checker on our website https://secure.europeanssl.eu/en/info/verifycrt offers you a more detailed check of the certificate chain.
If you have any questions or problems, our support team (firstname.lastname@example.org)will be happy to assist you.
