archieve manager does not archieve files
The archive manager does not archive files and gives an error message during the archive.
Archive: /home/roland/Downloads/InstallWoW.exe [/home/roland/Downloads/InstallWoW.exe] End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. zipinfo: cannot find zipfile directory in one of /home/roland/Downloads/InstallWoW.exe or /home/roland/Downloads/InstallWoW.exe.zip, and cannot find /home/roland/Downloads/InstallWoW.exe.ZIP, period.
