The Installer uses the version code to determine if you are doing a fresh installation or an upgrade.
If you execute the same Installer a second time, the Installer registers this and you will have the option to modify, repair, or remove. These processes are detailed below.
- Message Queues like wsworkflow, wsreporting, wsinfra, and wsautorunfile are created by the server Installer. If you delete any of these queues, you must recreate them by running Modify Server Installer.
- If Studio Manager Worker is installed on same machine, and if SAP GUI registry entries are modified after the Studio Manager installation, then the Worker installation will reset the SAP GUI registry entries back to zero.
