Error : Sitecore root certificate, Cannot validate argument on parameter 'Signer'

Error : Cannot validate argument on parameter 'Signer'. The "$_.HasPrivateKey -eq $true"
validation script for the argument with value "[Subject]
  CN=DO_NOT_TRUST_SitecoreRootCert,

I got above error while installing sitecore 9.0 update 1 on my system.

To fix above issue I just change one line in file xconnect-createcert.json.

Old "StoreLocation": "abc",

New "StoreLocation": "LocalMachine",

Now delete all sitecore root certificate available in your system and re run your script.

Happy Learning!!!
