E-Prime 3.0 requires the software license, either USB-based or Cloud-based (LICENSE: Understanding E-Prime and Runtime Licenses ), to be validated in order to utilize the software. The most common errors for USB-based licenses are failing to attach the USB HASP key to the E-Prime computer and needing to update the USB HASP driver. These and other reasons for license validation failures are described below. If the license is not validated, then E-Prime enters either Minimal Mode or a Grace Period, depending on whether the software license has ever been successfully validated. Unless noted otherwise, the information below applies to both USB-based and Cloud-based licenses.
E-Studio Minimal Mode
E-Studio enters Minimal Mode when the software license has never been successfully validated on the E-Prime computer. The following message appears which explains that the license cannot be validated and that the grace period is not available since the license has never been validated:
Minimal Mode offers signficantly reduced functionality compared to Grace Period mode (discussed below). The only functions that are available in Minimal Mode are the ability to see the Workspace, view the About Box, and exit the application.
The Registration dialog is presented every time E-Studio is opened in Minimal Mode. This dialog provides an alert to the user that a valid license needs to be connected to the machine when completing Registration (LICENSE: Registration and Validation ).
E-Studio Grace Period Mode
E-Studio enters Grace Period mode when a license has been previously validated but cannot be validated currently. Grace Period stays in effect until the license is successfully validated again.
The Grace Period allows the user to open, design, and save experiments within E-Studio without having the license connected. However, Grace Period restricts the number of times that these actions can be performed. Once the Grace Period is finished, E-Studio will enter Minimal Mode until a license is validated..
Licensing issues are mostly likely caused by one of the issues mentioned in the listing below. User who still encounter issues after reviewing this article should download and run the EPrime3LicenseDiag application while a license is connected to the machine. Several files are generated to the desktop which should be sent back to PST in a ZIP file.
NOTE: A support request can be submitted by navigating to the Product Service and Support site and selecting 'Submit A Request'.
USB License Key Issues
- The single user USB License Key is not connected to the machine. Connect the key to the machine and restart E-Studio.
- The machine cannot access the machine where the Perpetual Group USB License (i.e., Network) is hosted. Ensure the host machine is running and the client machine can access it. Refer to LICENSE: Group USB License (Network) FAQ and Troubleshooting  for more troubleshooting suggestions with Network Licenses.
Cloud License Issues
- The machine is not connected to the internet. E-Prime Cloud Licenses require an internet connection (LICENSE: Detaching a Cloud License ). Verify your machine is connected to the internet and reopen E-Studio.
- The Identity ID is disabled. Ensure with the Cloud License Owner / Admin that the Identity ID is valid.
- The Identity ID is being used on another machine. An Identity should only be used on one machine; not multiple machines. See LICENSE: Sharing Identities across multiple machines is not recommended  for more information.
- The Maximum Concurrent User limit has been reached. Each Cloud License has a Maximum Concurrent User limit that sets the total number of users who can access the Cloud License at the same time. Another user can close out of E-Studio to free a seat or additional seats may be purchased from PST.
- The Cloud License is expired. The Cloud License Owner / Admin can renew their Cloud License for another time period.
- A password is specified in Localhost (LICENSE: Localhost password prevents Cloud License ). Disable the password to access the Cloud License.
General License Issues
- A HASP driver is not installed or properly configured. If HASP/SafeNet Admin Control Center cannot detect a license, then install the latest HASP/LDK driver, see LICENSE: Downloading the latest HASP driver . NOTE: A reboot of the machine may be required after installation.
- There is an issue with the E-Prime installation or an incomplete upgrade from a previous version. This may cause licensing services to not function properly. Uninstall E-Prime and then remove any files from the E-Prime installation folder (default location: C:\Program Files (x86)\PST\E-Prime 3.0). Then, reinstall and attempt to license the machine.
- The HASP service is being blocked. Disable any firewall or antivirus programs that may be active on the machine.
- The HASP service is not started or is not running. Check to see if the 'Sentinel HASP License Manager' or 'Sentinel Local License Manager' is running by navigating to the Start menu > Run > services.msc. If the service is listed but stopped, start the service by right-clicking and selecting 'Start'.
