Step 2: Install and Start Respondus LE

Use Windows' My Computer or Explorer to locate the RespondusLE.exe file downloaded in Step 1. Double-click the file to start the Respondus LE installation program. Several screens will guide you through the installation program. Once Respondus LE is installed, start the program by double-clicking the Respondus LE icon that is now located on the Windows desktop. Or follow these steps to start the software.

  1. Click [Start] from the Windows desktop
  2. Click [Programs]
  3. Click [Respondus]
  4. Click [Respondus LE]

The first time you start Respondus LE (and each time thereafter until the program is registered), you will be presented with a screen that provides the "Product ID#." The Product ID# is used in Step 3 to obtain the password required to activate the software.

Step 3: Register Your Copy of Respondus LE

Register your copy of Respondus LE. You will be asked to enter information about yourself, including the Product ID# (see Step 2) and a valid e-mail address. (We do not sell e-mail addresses or customer information to third parties. See our Privacy Policy.) Once the registration information is submitted, the password is immediately sent to the e-mail address you provided.

Step 4: Enter the Activation Password

Once you receive the password by e-mail, it must be entered into the Respondus LE program. If you haven't done so already, start Respondus LE (see Step 2). Enter your password when prompted (you may want to "copy and paste" the password from the e-mail message in order to prevent typing mistakes). Click [OK] to continue. The Respondus LE software is now activated. You will not need to repeat Steps 1-4 in the future, except when upgrading to the latest version of the software.
