Hi Ilove,
I did some further checking at GitHub and found the code for the desktop
version of cr3 and discovered that the original source for download is here-
https://sourceforge.net/projects/crengine/files/
It's the latest version 3.3.61.zip: Some further thoughts, being that it is
designed for 32bit and you're running 64bit, after you have a clean DL,
right click on the file ~Properties ~then see if there is a setting to run the
32bit software on your 64 system (I know I had something like that on
my old WinXP Pro anyway.) Perhaps it was only that after all.
Hope it works,
