Hello I am using exiftool.exe v 6.91, Windows XP and 2000. When i try to modify the value of an existing IPTC tag. eg: exiftool -IPTC:City="Test" essai.jpg I get the following error message: Error while attempting to call Image::ExifTool::Photoshop::WritePhotoshop Can't locate Image/ExifTool/WritePhotoshop.pl in @INC (@INC contains: CODE(0xf92fcc) CODE(0xdccda4) CODE(0xdccedc)) at (eval 26) line 1, (EXIFTOOL_FILE2) chunk 11. (no problem for modifying EXIF and XMP fields) the file WritePhotoshop.pl exists in my temp folder (c:/temp/par-Jean/cache-exiftool-6.91/inc/lib/image/ExifTool/WritePhotoshop.pl)
