Hi Joe,

I even set the full path to gswin32c.exe in my .emacs.

I have to add that the pdfsizeopt worked for many years, even under Windows 
8.1 I had to install freshly and run into this issue.

By the way, in my .emacs I set up a shortcut this way:

(eval-after-load "tex"
'(add-to-list 'TeX-command-list
'("pdfsizeopt" "pdfsizeopt.exe %s.pdf %s.pdf" TeX-run-command t t :help "Run 
pdfsizeopt.exe") t))

But as mentioned, I did that for years...
