After clicking on the above link, select 'Open file' in your browser. If you instead elect to 'save file' to the 'windows\desktop' folder, look for the SIMPLEMJ.EXE icon. If you download to another location, find and run file SIMPLEMJ.EXE in "My Computer".
When the default installation folder is displayed, change it to your main picture folder. Pictures may be viewed from anywhere, but to take advantage of SimpleMiser's built-in simplicity, additional picture series should be stored in folders inside the main picture folder where MISERJPG.EXE is located.
