Just did a new clean installation and upgrade to 7.1 on Win 10 Pro, and got the same error. Tried reinstalling the program and still got it.
Edit: I tried to download the file as descripted above, did not work, and tried to install the shutdown program and that did change the error message to:
Error 53 ...
File not found: Planetjpeg\a11.jpg
Still do shut down after pressing "ok"
Edit2: Got it to work, just needed to move the pictures from the 7.10 update into their folders.
