This doesn't sound like it has anything to do with Python at all.

What is your converter?
How are you trying to open the file? Double-clicking (that's my bet),
choosing Open from the WinRAR menu, right-click in Windows Explorer, or

This sounds like Windows is trying to run the Java file rather than open
it in WinRAR. If you google on the error message:
"failed to load main-class manifest attribute from"
you'll find lots of questions that basically say "Whenever I try to run
my .jar file...". So I'm pretty sure that you may have *installed*
WinRAR, but you're not *using* WinRAR.

Lesson one: Google on the error message.
Lesson two: you need to be more specific in what you're doing. It's not

but are you sure you're succeeding? Is there any sign that WinRAR is
