Logging
Examine the install_root/logs/uninstlog.txt file to verify that there were no file system or other unusual errors while uninstalling. If there are problems, correct them, and uninstall manually before reinstalling the product.
After uninstalling a WebSphere Application Server product, delete the installation root directory before reinstalling into the same directory. Deleting the old directory avoids XML configurations that are not valid that result from retaining old files. To delete all files so that you can reinstall with a clean system, see Uninstalling manually.
