no output using crop

6.9.5-7 is the most recent cygwin-version.
7.0.5 is the windows installation. These really should not interfere.

Be sure your convert is the ImageMagick convert and not the Windows convert.

check! Is working correctly. The problem is with cygwin's ImageMagick

Also be sure your input and output images are in your working directory from which you issued the command line. Be sure you have read and write permissions for those files and the directory and execute permissions to run the command.

check! Otherwise convert without -crop wouldn't create an output file.

6.9.5-7 is the most recent cygwin-version.
7.0.5 is the windows installation. These really should not interfere.

Why shouldn't they interfere? Both versions are executable files, with associated DLLs, XMLs etc. Both should be executable under Windows CMD, Windows BAT, Cygwin bash, or many other shells.

It is possible to run multiple versions of IM under Windows CMD, Windows BAT or Cygwin bash etc, but it's a bit complex. I suggest that you first ensure that only one version is installed, and get that working. When you've done that, you can install multiple versions, if you want.
