You aren't giving much information that pertains directly to your situation. Are any of your folders mojibake? The linked thread seems to conclude to just rename the containing folder to anything else.
Yes. 2 of them. The first folder, containing the .exe among other things, and the one inside said folder that isn't resource or script. Contains read me and another file.
Anything else...? but I tried it. I'll try again.
EDIT: didn't work.
2 text documents are also in mojibake.
