edit object tool - pdf files

[rose123123]

I need to edit pdf files, colours, photos.
I get this error message when I do:

Acrobat cannot start the object editing application you've specified. Verify the object editing application location on the TouchUp panel in Preferences.

I have selected illustrator to edit.

Illustrator is not a pdf editor.
you may need an application like PDFPen

Illustrator is not being used as a PDF editor here. Illustrator is editing an object passed off by Acrobat. Under normal circumstances, this should work and is the ideal method for editing PDF content.

Try starting Illustrator before attempting to edit the object in Acrobat. You might also repair permissions on your system.

Is the object a vector graphic or should it be edited in Photoshop?
