jpegtran.exe: can't open c:\output.jpg for writing

[bflost]

Using the parameter example: python dezoomify.py http://www.bl.uk/onlinegallery/onlineex/evancoll/a/zoomify72459.html c:\output.jpg

I am getting the error "jpegtran.exe: can't open c:\output.jpg for writing."

I am using the jpegtran.exe from sourceforge.

Thanks

The root C:\ directory is usually write protected and can only be written to when the program is run with elevated privileges. You could either run Dezoomify from an admin-mode command prompt (look for "Open command prompt as Administrator") or use another directory that is not write protected.
(Or the problem might be something else entirely, I suppose.)
