There should be a file called "commons-io-2.4" in your libs folder.
At least it is there after a fresh install of Minion 3.0.5 (before the update is applied):
And this is the same folder after I had started Minion and the update was downloaded and applied
If any of these libs are missing for you try to change the folder where you install Minion to to e.g. E:\Minion (not within the users or programs folder) AND create the folder before installing it + add the whole folder & subfolders to the whitelist of your antivirus tools.
Check if this solves it. Maybe the files got blocked during install already.
Also re-download the latest Minion 32bit installer from the website to make sure you got the correct file:
