E-Prime Go 1.0
PcQualify is an application to quickly verify if a machine meets the minimal requirements to run E-Prime Go 1.0 / E-Prime 3.0.
NOTE: This application does not test the timing of a machine.
PcQualify checks six specific requirements to run an experiment.
- Display Device - If the machine is running Windows 7 SP1, it checks that the machine meets DirectX 7 requirements. If the machine is running Windows 8 and beyond, it checks that the machine meets DirectX 11 requirements. If "NO" is returned, E-Prime cannot be run. Workarounds include trying to update the driver, replacing the video card with a newer one, or using a different machine.
- Sound Device - This is only required if the experiment has the sound device enabled (checked) in the Experiment Object Property Pages > Devices tab. If "NO" is returned and a sound card exists, ensure you have the latest sound card driver installed. On some machines, headphones or speakers must be plugged into the audio jack.
- Windows Updates - This is only required if running on Windows 7 SP1 and using Automated Mode. Certain Windows Updates are required on Windows 7 SP1 when using E-Prime Go's Automated Mode. If "NO" is returned, run Windows Update until "YES" is returned when ran.
- System Memory - The machine should have at least 4GB of RAM. Running below spec is not recommended. If "NO" is returned, add more RAM to the machine or use a different machine.
- Free Disk Space - The machine should have at least 1GB of free space available. If "NO" is returned, free up disk space on the machine (e.g., empty the Recycling Bin, delete unused files, uninstall unused programs, etc.).
- Accurate System Time - This is only required if using Automated Mode, accessing www.eprimego.com, or uploading any experiment/data. If "NO" is returned, sync your system clock with a NTP server. For more information on how to sync your clock, see https://www.tenforums.com/tutorials/6410-synchronize-clock-internet-time-server-windows-10-a.html.
The application returns "YES" for all categories listed above if the machine meets the requirements of PcQualify.
In the image below, the machine passes everything except Display Device. This machine is running Windows 10 and requires DirectX 11 support. Because the latest driver is installed, the only options are to upgrade the video card (to a newer one) or use a different machine.
NOTE: E-Prime is intended to be run on a native Windows machine. Running in a Virtual Machine or on Remote Desktop results in an error and are not supported.
