Kindlegen giving weird error

Hi guys, since a while exporting in .mobi has become a problem. I never had an issue with it until 2-3 months ago.

What I get is this message:

The file at “/Users/myname/Dropbox/Backup Mac/Documenti/KindleGen/kindlegen” does not seem to be a valid KindleGen file. Please try re-downloading and re-installing KindleGen.

I’ve been updating kindlegen, run it in terminal, checked if the path is correct, but I still get the same error. Is there a more recent kindlegen than those listed here?

Ok, this has been solved.

For future reference, move your KindleGen folder under /Applications and it works again.
