Installed Imagemagik (all 112 MB of it!!), installed MSI v8.8.7, sorry to have to report that it's still not working.
I'm launching using the "right click + left click" method.
It goes from "retrieving data" to "All data acquired" almost instantly, and then just sits there, doing nothing.
The generated MPL file only contains a single "</MPL>" and each failed attempt adds another on a new line.
Just to be sure, I reinstalled imagemagik taking the non-default "install OLE support" but that did not help, it's still not working for me.
One thing I did notice, not sure if it means anything, but...
Going back to v6.7 still works fine. When using the right click + left click method for launching the program, there is no MC context menu shown when releasing the right mouse button with 6.7, but when using 8.8, the MC right click menu is shown when the right mouse button is released. I tried using the autohotkey file from 6.7 with 8.8 but it still did not work.
I've now uninstalled imagemagik... out of curiosity, why would your program require imagemagick:
ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.
