More About the Registration Process

The Performance Estimators registration process consists of three steps:

1. Complete the online registration. Each user must register individually. If you have previously registered for any GE online application, you can simply update your profile to include this new application. Otherwise, you must go through the full online registration process to establish a username and password to login.

2. Complete the GE Software License Agreement. The Performance Estimator software is licensed for use by individual companies. Each company must have a signed agreement on file for its employees to download and use the applications. If someone from your company has not signed an agreement, we will send an agreement for you to complete and return as part of the registration process. You may download a copy of the GE Software License Agreement (65KB PDF) for review prior to entering the registration process.

3. Obtain approval from your GE Sales Manager. Your GE Sales Manager must give approval for you to access these applications. During the registration process, you will be asked to identify your GE Sales Manager. We will contact him or her directly to obtain the necessary approval.
