It seems like a problem specifically with the rename function (and maybe the delete function), because -overwrite_original_in_place is able to open the original file for writing.

So I think it comes down to something different about your operating system. What OS are you running? Also, what version of ExifTool (the stand-alone Windows version 6.90?).

It must be something very specific to your system because I haven't seen this problem before.

Also, do you have Perl installed, and did you ever install any other versions of ExifTool using a different installation technique? (I'm wondering about possible library conflicts between versions.)
