Files are not deleted after unzip

For some time I can see that downloaded ZIP files are not removed after installation. There is no any error message. It worked earlier. Strange :)

I have seen this a lot of times. Often it is related to windows filehandling and maybe some 3rd party software eg virus protection that holds on to the filehandle.
But maybe the file deletion could be done with a shutdown hook...

Can it also be related to issue #13 ?
