Following your original directions, no matter how many times reboot was performed the same error message displayed.
Today, reran the batch file multiple times and the eEye folder was still there. Deleting the folder was not permitted. Reran the batch file in SAFE MODE and the eEye folder was still there. In SAFE MODE renamed the eEye\Blink folder to Blink_old.
Rebooted and ran install again. Blink successfully installed.
I appreciate your assistance.
