I already have one instance of Sitecore 10.3
and when I am trying to install another one I'm facing the following issue:
Cannot retrieve the dynamic parameters for the cmdlet. Cannot validate argument on parameter 'Source'. The " Test-Path $_ -Type Leaf " validation script for the argument with value ".\createcert.json" did not return a result of True. Determine why the validation script failed, and then try the command again.
Can we only have one Sitecore instance in a machine? Do I have to remove the old one to have a new instance?
.\createcert.json
exists where expected. 2) You are running the commands as an Administrator. 3) Your script execution policy is permissive enough.
