Step 1: If you already have (or had) a working version of PIDtoolbox, you do not need to re-install the Matlab runtime.

Step 2: After you download the PIDtoolbox_v0.58_win.zip file, unzip and drop the enclosed 'PIDtoolbox_v0.58_win' folder 
and all of it's contents onto your desktop. It is best to run PTB v0.58 directly from the 'PIDtoolbox.exe' that is located 
in the subfolder called 'main'. I realize that the initial installation using the 'MyAppInstaller_web' app automatically 
places PTB and it's contents under the 'program files' directory. But DO NOT use the executable (or shortcut to it) that is 
under the program files directory please! Instead, run PIDtoolbox.exe located in the 'PIDtoolbox_v0.58_win/main' folder that you downloaded.

Step 3: NEVER place log files in the 'PIDtoolbox_v0.58_win/main' folder! 
You may place log files in any other folder with full read-write access. 
You no longer need to copy the Blackbox-decode.exe in with your logfiles. 
This is all taken care of by PTB.

NOTE: PTB creates a couple of text files containing logfile directory information 'logfileDir.txt', and PTB default information 'PTBdefaults.txt'.
If you notice PTB not saving your defaults or going to an incorrect directory, it might be seeing an old version of these text files in a different folder. 
To avoid this possible issue, delete those files, and/or replace existing PTB version and contents with this one by simply replacing the entire 'main' 
folder of older version with this one. This will help avoid any such confusion. This is another reason it is good to simply place the 'PIDtoolbox_v0.5x_win' 
folder and all of it's contents onto your desktop so you can simply replace older versions by deleting them from your desktop.
