Continuing my voyage of obscure-error-discovery around Sitecore 9, this week SIF has been putting a lot of red into console windows for me. I'm not sure how many people will have this scenario, but if you have multiple people who all need to install their own Sitecore 9 instance onto one machine, this may be of interest:
Working in a web agency we have multiple development teams who share development and test infrastructure. Up until now we've been happily installing multiple instances of Sitecore onto web servers without issues using SIM. But recently I was the second person to try and use some shared scripts to install a site via SIF onto one machine. And it was not happy.
The first step in the SIF process is to generate the certificate used to communicate with xConnect:
#install client certificate for xconnect $certParams = @{ Path = "$PSScriptRoot\xconnect-createcert.json" CertificateName = "$prefix.xconnect_client" } Install-SitecoreConfiguration @certParams -Verbose
But that bombed out for me. The logs included:

A bit of googling for that error brought up a Stack Overflow post that explained the background: What Powershell really means is "I asked the cert store for a specific certifciate ID, and I got back more than one" – and you can't use a list-of-certificates where the script expected a single certificate...
You can see this in the log output, because there are two cert thumbprints listed:
VERBOSE: Found Cert with thumbprint: 763C0AA20CB3A8038928AC09CDD6DF2F7CFB2EBA 27A5D8877F35151B0DA7A27B8BDFA44B0006CB47
Following the comments under the accepted answer, I deleted the "newer" of the two certificates, and tried to work out what was going on. The SIF script had created a new version of the "DO_NOT_TRUST_SitecoreRootCert" certificate – which didn't entirely make sense to me. That should have already existed, since there was already an instance of Sitecore running happily on the machine. And looking at the certificate store for the local machine, it was indeed there:
Seeing that, the first idea that popped into my head looking at this was "ah – perhaps that needs to be in my store as well?" so I copied the root cert from the machine store to my store. That got me a different, and equally obscure error:
For the benefit of Google, the error this time was:

At least this time it's only reporting a single certificate thumbprint – so it's a step forward at least. Now, the important message this time seems to be "The certificate does not have a property that references a private key" – and if you go and look at the details of the root certificate in the trusted store, you'll see that it does not have a private key attached:
That makes some sense – you can't use the "root" certificate to sign anything if you don't have its private key. Signing relies on the private part of a key for its security.
Checking with the person who'd done the first SIF install on this machine, their copy of this certificate did have a private key.
...that if you're part of a group of devs who are sharing some "standard" SIF scripts and you happen to be the second (or subsequent) Windows user to install a Sitecore instance on a machine using them, you need to ensure that you have a copy of the original root certificate, which includes the private key.
You can get that by asking the user who did the install first to export it for you, from their personal certificate store:
If they export the certificate including the key, and you import it into your store, then the SIF script will complete successfully.
Now I know where the error is coming from, I guess there are some other approaches that could be used to solve this. Whether these are relevant to you probably depends on your precise working patterns with multiple installs:
