To facilitate secure communication between Execu/Tech software and Shift4's i4Go V2 service, HTML and Javascript are used. Because of this, you may experience some errors related to Internet Explorer Trusted Zones after updating to i4Go V2 or installing a new terminal. This is typically because Internet Explorer Enhanced Security Configuration is enabled. While you can disable this, it is preferred that you tell your server or workstation that the updates are safe to run. 

The latest version of ETRegister will address these issues, so try running it, first. Register Programs and Controls

If these steps don't solve your Enhanced Security configuration issue, we recommend that you use our hosted form. This is how you change the URL Shift4 i4Go V2 PMS / POS Settings Here are a couple points to keep in mind. The form is hosted on a secure server (https://www.execu-tech.com) The form is identical to the local form The form doesn't send cardholder information to us or through us, only to one of Shift4's secure servers. The form is loaded into the workstation's memory from our secure server. The cardholder information is sent directly from the workstation to one of Shift4's secure servers. Shift4's secure server returns a token to the workstation which is then stored by the Execu/Tech application.
