title: How to convert .crt cetificate file to .pfx
body: <p>I want to install the '.crt' certificate I received from a certificate provider to my IIS 7.5 server.
  I have tried many times to install the .crt file by clicking on the 'certificates', and it states that it is installed correctly. So I open IIS, select "my server", open "server certificate" which is available on the menu on the right side, click "complete certificate request", select the .crt certificate on my computer and click ok. However, when I refresh IIS the certificate disappears automatically.</p>
  
  <p>Our hosting provider mentions that I need to use a '.pfx' file which I do not have.</p>
