How to Completely Uninstall Puppet
PeopleSoft DPKs use Puppet to automate the installation of software and deployment of PeopleSoft domains and PeopleTools. When you perform installation using any PeopleSoft DPK, it installs Puppet on the computer or server if the appropriate version is not present already.
Usually you won’t have any issue with the Puppet software but there are some cases wherein you may have issues for example when performing cleanup of a higher PeopleTools and installation of a lower PeopleTools release. You may also have issues when re-purposing a server or a computer.
For example, one of the errors you may get is:
Invalid Puppet version or left-over directory and registry key exist. Please refer to the log for details.
To resolve this issue and similar issues, you may need to uninstall Puppet completely.
