After running the full uninstaller for CAPC, and/or deleting the /opt/CA/PerformanceCenter directories it still does not allow you to reinstall CAPC.
This is because there are still some references of CAPC being installing in other directories and files, which the uninstaller may not fully cleanup.
After running the full uninstall as documented in the CAPC installation guide, open an SSH session or the Terminal locally on the server and run the following commands in order.
rm -rf /opt/CA /var/.com.*
rm /var/.com.zerog.registry.xml -f
rm -rf /opt/CA -f
rm /etc/init.d/caperfcenter* -f
rm CAPerfCenterSetup.bin -f
#shutdown then reboot
shutdown -r now
Once the server comes back online, attempt the installation again.
