After downloading Quickmap data, you may get this error when you try to run the file:

Quickmap Data Setup

Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.

End of Central Directory record could not be found.

This is because the download is corrupt. Try downloading the file again (you may need to clear any cache that might be caching the invalid file, such as on a caching proxy server). Failing that, contact Quickmap for a different type of download file (exe / zip file) to ensure that your download isn’t cached and reduce the chances of antivirus corrupting the file during the download.
