Analysis failed: The package "modules.packages.rar" start function encountered an unhandled exception: Unrar not installed? (rarfile.UNRAR_TOOL='unrar')

I have a windows xp virtualbox, I had installed winrar 3.2 and python-rarfile, but when I submit a x.rar file, the virtualbox shutdown and raised a error: Analysis failed: The package "modules.packages.rar" start function encountered an unhandled exception: Unrar not installed? (rarfile.UNRAR_TOOL='unrar'). Then I followed the rarfile API, I set down rarfile.UNRAR_TOOL('C:\Program file\winRAR\UnRAR.exe'), but this time it raised an error: Analysis failed: The package "modules.packages.rar" start function raised an error: Unable to execute the initial process, analysis aborted.
I don't know how to deal with it.

perhaps your filename has some Chinese characters?
