What are the system requirements for HyperSend?

You can track deliveries or send messages from any web browser that supports secure connections (SSL) and JavaScript. This includes most current browsers for Microsoft Windows platforms.

To send files, or pick up files, you must be running HyperSend. HyperSend is a small component that resides in the system tray. You log HyperSend into under the identity (email address) you used when you signed up for an account.

When deliveries are ready for pickup, HyperSend downloads them to your system and stores them in your Local Inbox. When you create deliveries which include files, HyperSend uploads the files to the server.

To obtain a copy of HyperSend (it's free) and to learn more about the required operating system and browser specifications, go to the support tab on

I am receiving a Windows Security Alert. What should I do?

If you are receiving a Windows Security Alert that indicates: "Revocation information for the security certificate for this site is not available. Do you want to proceed?" [Yes] [No] [View Certificate], then HyperSend is stalled and cannot reach until the dialog is dismissed.

Explanation & Resolution - The interactive dialog appears as a result of a security setting enabled in Internet Explorer. This is a default setting in IE v. 7.0. Select Yes to proceed. This issue is caused when HyperSend cannot communicate with the Certificate Revocation List (CRL) servers which are outsourced by Verisign, the issuer of the server certificate on If HyperSend cannot communicate with these servers, an error message will be displayed and must be dismissed before processing will continue.

This may happen if the CRL servers are down (or access to them is blocked) and the "security check" is not in the browser's cache (perhaps because https caching is disabled).

The only work-around here is to TURN OFF Internet Explorer's revocation list checking. This is done in the IE settings Tools | Options | Advanced. Look for "Check for server certificate revocation" and make sure it's unchecked. Click 'Apply'. You must close and restart Internet Explorer for the change to take effect.

Warning: This is a default setting in IE7. Periodic updates to IE will turn this setting back on. Review the setting after any Windows update has been applied to the system.

What special software do I need to use HyperSend?

The HyperSend service is comprised of a web page and a piece of software called HyperSend. Using HyperSend requires the installation of HyperSend - a tiny component on your PC which resides in your system tray next to the clock. This Agent is responsible for transporting files to and from your computer. This small downloaded component is under 400K in size and, when idle, appears in the system tray as a yellow triangle icon.

The account confirmation process directs you to the installation of HyperSend. A button on the support page, 'Download and Install HyperSend, will take you to the "Get HyperSend Agent" page. The 'Download for Windows' link at the top of this page provides access to a page with a four-step list of instructions. Follow this link to download HyperSend. Then click the 'Click here' link in step 1 on the page:

What Browser Security Settings Are Required?

Some features of the HyperSend program, such as the checkboxes on the Pick Up and Track page, will not function properly if JavaScript is disabled. Other functions of the web site such as login, requires certain ActiveX settings also to be enabled.

If you wish to make sure that these settings are properly enabled, please check the following locations. If you are using Microsoft Internet Explorer, go to the Internet Options by right-clicking on the Internet Explorer icon on your desktop and choosing Properties or go to Control Panel and double-click the Internet Options icon. Go to the Security tab and click on the Custom button. Make sure that the following settings are NOT disabled. They can either be set Enable or Prompt:

  • Scripting of Java applets
  • Download signed ActiveX controls
  • Active Scripting
  • Run ActiveX controls and plugins
I recently got a new computer and no longer have HyperSend. How can I get HyperSend again? Do I need to sign up again?
No, you do not have to sign up for a HyperSend account, because your account is still open and active. You only need to download and install HyperSend again.
Why is the Compressed size the same as the original size on some deliveries?

The Details page for deliveries shows the original file 'Size' and the 'Compressed Size' for each file. If these two file sizes are identical, it is likely that compression was not enabled for this delivery.

There are three possible reasons for this:

  1. Compression is set to OFF in 'Account Settings' found on the Options Tab.
  2. The file is already compressed. If this is the case the compressed file will be similar size or larger. Since we do not charge more capacity if compression enlarges a file, we will just display the same size.
  3. The recipient has an older, out of date Agent. HyperSend Release version 2.0 (build 40) included a new improved compression method. Since older Agents cannot decompress the new format, our server automatically detects this and disables compression for that delivery. Have your recipient check their Agent version by clicking on HyperSend (yellow, triangle shaped icon in the system tray). and select 'About' from the menu.
