2 - Click File, Add/Remove Snap-in
3 - Click Add
4 - Select "Certificates" and click Add
5 - A wizard will open. Select computer account and click next
6 - Select Local Computer and click finish
7 - Click close
8 - Click Okay
9 - Expand Certificates on the left hand side of the console window
10 - Locate the personal certificate folder, right click on it and select import under all tasks
11 - Locate the certificate you need to export in the personal folder. Right click on it and select export under all tasks.
12 - In the export wizard, select the option to export the private key
13 - Select the file format to be PKCS#12 and check off "Include all certificates in the certification path if possible"

You can now take the exported .pfx file and move it to the IIS 7 server.
