My Download Won't Start or is Getting Interrupted

The Download Email you receive after your order/trial request will contain a link – this link will open the MaptitudeDownloadManager program, which will start the download. For steps on using the download manager, see: https://www.caliper.com/learning/articles/downloading-from-a-download-link/

Sometimes, an antivirus or firewall will block the program from running which will stop the Download from starting. You may get an error such as “Cannot establish a connection to https://usercenter.caliper.com”.

This article goes over some potential fixes we recommend trying:

Disable any antivirus software

Your software license is stored in several files on the computer, and these files are encrypted. It is possible that antivirus software could detect one of these files as suspicious and either delete it or quarantine it, thus causing the license check to fail. Please try temporarily disabling the system’s anti-virus. You should do the same for any spyware software you have installed.

You may also try exempting the “C:\ProgramData\Caliper” folder from your anti-virus software to prevent license disruption.

Disable automatic backup software

Certain automatic backup software operates by monitoring all file access and attempting to backup any files that are being edited. This can interfere with the license software and cause a failure.

You may also try exempting the “C:\ProgramData\Caliper” folder from your automatic-backup software to prevent license disruption.

Try a different browser

Often failed downloads can be resolved with a different browser. If, for example, you are using Internet Explorer, try Firefox or Chrome. Also, try opening the link in an Incognito window. For example, in Chrome/Gmail you can do this by right-clicking the download link and choosing “open link in incognito window”.

Check your internet connectivity

Verify that you are connected to the Internet by trying to access some websites.
Try the download again from a different WiFi network or try the download over a wired connection.

Verify hard disk space and folder permissions

Make sure that you are downloading files to a folder on your hard drive.
Verify that you have enough space on your hard drive. If necessary, remove any unnecessary files and clear your default TEMP folder to free up disk space.
If a permissions error occurs, make sure that you have write access to the folder to which you are downloading.

Update your virus software and scan your computer for viruses

Certain viruses look for encrypted files deeming them important, and then they intentionally delete them or corrupt them. This would adversely affect your software installation.

Try using a Proxy Server

Certain networks block any traffic that is not routed through a proxy server, so you may need to configure the download manager this way
