I just re-read one of your earlier posts, and realized that you're using another script which relies on the ExifTool libraries. If this is the case, my previous advice won't work, and you must install the libraries in a standard location.

The trick then is to figure out where ExifTool is installed, then copy all files in the "lib" directory over top of the old ExifTool installation. You can list the Perl library include path like this:

Look for an "Image" directory containing "ExifTool.pm" in the listed directories (check the directories in order -- you only need to replace ExifTool in the first directory that you find it). Then copy Image\ExifTool.pm and the entire Image\ExifTool directory over top of the old files you had installed. You may also want to copy File\RandomAccess.pm over too, although it is likely this file didn't change.

A bit trickier, but still not too difficult.
