When installing an SSL certificate using Microsoft IIS 8.0 Manager, the following error message may be displayed even though the installation is successful:
This issue occurs because IIS Manager performs a lookup operation to look for a friendly name of the certificate during the installation. However, the code that performs this lookup operation misses this specific case, and it does not know how to retrieve the friendly name of a certificate in a PKCS#7 file. Therefore, the lookup operation fails, and the error message is displayed.
Check to see if the certificate was installed by performing the following steps:
Step 1: Create a 'Certificates' snap-in within the MMC
From the server:
Step 2: Locate the SSL certificate
On the General tab, under the validity dates, there should be a key with the following message:
"You have a private key that corresponds to this certificate"
Note: If this is present, close the certificate and the MMC and proceed to Step 3. If there is no reference to the key, please follow these instructions to try and restore the private key: SO21613
If unable to restore the private key, the certificate will need to be replaced.
If the certificate needs to be replaced, please create a new CSR on the server by following the instructions in Knowledge Base Article SO21229. Once the new CSR has been created, replace the certificate by following the instructions in Knowledge Base Article SO13487.
Note: If the SSL certificate was issued from an Enterprise account, follow the replacement instructions referenced here SO12917
Step 3: Bind the SSL certificate to the web site in IIS
