please note that i have deployed the SAE version 3.5 through ePO. then, i have run the uninstall task through ePO as well. However, some machines could not uninstall and i could not uninstall it manually. please refer to the image.
Try disabling Access Protection during the uninstall. If that doesn't work reboot into safe mode and disable the service then reboot back into normal mode and attempt the uninstall again.
