Msvcrt10.dll is only needed by FilterFactory plugins. FilterFactory plugins can be recognized by their zoomless preview, up to eight sliders with a triangular knob and a file size of 49,152 or 56,344 bytes.
My next questions are:
which plugins need msvcrt.dll?
which need msvcrt20.dll?
and which need msvcrt40.dll?
I've got all of them in my Windows/System folder, but I'd like to know which dll goes with which of my plugins. Thanks again.
