Error "Could not initialize installation (CRC)" during installation of SQL Navigator.
This error is usually due to a corrupt or incomplete download of the installation file, although the OS reported that the download has completed.
Try to reset the Internet Explorer settings via Control Panel > Internet Options > click on the "Delete Cookies", "Delete Files", "Reset Web Settings" under Programs Tab, and "Restore Defaults" under Advanced Tab. Try the download again to see if it will now work.
If the above still does not work Contact Support for further assistance.
