Somehow in trying to cleanup my computer's hard drive, I have inadvertently corrupted WordPad, which I have long used for viewing many types of files, including logs (i.e., log4j).
Now, when I right click one of these files and choose "Open with" and "WordPad", I get an error:
fn is not a valid Win32 application).
I've researched this issue, tried reinstalling
wordpad.exe, but I still get the same error.
