Advanced Options

The Downloader has several advanced settings for server and download preferences. These are available under Options>Advanced.

Delete Compressed Files After Extracting Contents

Accessory files are packaged as self-extracting archives that will extract automatically once download is complete. The default setting is to delete the compressed file after download. If you want to keep the compressed file, uncheck the Delete Compressed Files After Extracting Contents option.

Automatically Overwrite Existing Data Files

If checked, the option to Automatically Overwrite Existing Data Files will delete any compressed file originally present in your download folder, if the Delete Compressed Files After Extracting Contents is unchecked.

Download Options

The Downloader default setting is to only look for files on a preferred server. When Downloader is launched, it selects a preferred server based on speed. To change the preferred server, click on one of the servers listed in the Available Servers list, then click the Set as Preferred button. It is recommended that you select the server that is located closest to you. Any changes will take effect the next time Downloader is launched.

 It is also possible to change the default behavior to look for files on all available servers, by checking the Look for Files on All Available Servers option. Since some servers may be geographically far away from your location, this may slow down the Downloader as well as the actual downloads.

If you are experiencing problems downloading from behind a firewall, you can force the Downloader to use HTTP protocol, which may remove download problems related to firewall issues. To do this, check the Force HTTP Downloading option.


If Downloader is giving you trouble, you can also manually download database, expression and MAPP files from this site.
