How to extract on the Desktop on Mac?

[julia_f]

I would to extract the archive on the Desktop on Mac cuz the software cannott extract on @ApplicationsDir@ because the software doesnt have the admin rights to modify the ApplicationsDir 's files during the software execution.

I write the following code :

Component.prototype.createOperationsForArchive = function(archive)
{
   conponent.addOperation("Extract", archive, "@DesktopDir@");
}

And I have this error :

Error during installation process (com.mycompany.software) : Error while extracting 'installer://com.mycompany.software/0.0.8mysoftware.7z': Internal code : E_FAIL

Does someone know how to fix this bug?
