You can find generic instructions for uninstalling CentraSite in the webMethods Installation Guide, which you can find at http://documentation.softwareag.com/. Basically, this entails invoking the webMethods Uninstaller.
However, you should be aware that uninstalling CentraSite does not delete the CentraSite database (Registry/Repository). There are many circumstances in which you should retain the database after uninstalling CentraSite; for example, if the database contains information that is important for your enterprise.
If you do wish to delete the CentraSite database, we strongly recommend making a backup copy of its contents before you proceed. Then delete the directory <CentraSiteInstallDir>\data.
