Hi Kirk,
For me the msvcrt-ruby 18.dll is there, in the same folder as Photo Mechanic.exe, and PM runs fine. I am getting the error when I try to open an image that I've saved from within PM to my desktop. I just played a little more and doubleclicking the file generates the error, but if I right click and Open With Irfanview, it will open. Maybe just the double-click is broken.
(I wanted to send a picture to my mom, and she only knows how to doubleclick, hence that is why I was checking.)
PWPro is Picture Window Pro, an image-editing program. I launch it from within PM to do editing, and doing a Save As from within PWPro to my desktop resulted in the same error. And funny enough, if I load PWPro directly and browse through my photos and select one to view and resave, it also has the error message. Somehow PM must be set as my default viewer and then when it doesn't find the dll because the pictures are on a desktop, not the PM folder, it just errs out?
