This is the most common issue, but also the easiest one to resolve. First, unplug everything from the Cronus Zen, press and hold the small blue reset button found underneath, then connect the short micro-USB cable from Zen's rear CONSOLE USB Port to your Windows PC (or a Mac running Windows) - Keep pressing the reset button until 'Zen Bootloader' appears on the OLED screen. If your USB cable is functional, the firmware update tool will detect the Cronus Zen hardware.
If you are running a newer version of Zen Studio with an older firmware that is not compatible, you will see this warning popup telling you that you must update your firmware.

If the Zen firmware version is showing as 0.0.0, it means it is corrupt (interrupted programming, bad USB cable, bad USB port) you should downgrade the firmware 👇
If you get a Network Error it's usually caused by one of these:
You are using Windows 7 and didn't install the driver patch from our Downloads page
Not connected to the internet or your modem needs resetting
Security software is blocking the download (Temporarily disable Anti-Virus and/or Firewall)
Your ISP is blocking access to our server
If you have tried all of the above solutions and still see this error (in particular trying another USB cable or USB port), it usually means there is a hardware fault that cannot be recovered and unfortunatley must be returned to your point of purchase for a replacement under its warranty.
There's a number of reasons you may see an error code on Zen's OLED screen (E2021, E3001...), it could be that you haven't updated to the latest firmware (Step 1 out of the Box), or perhaps loaded a bad script that has been written for CronusMAX but not Cronus Zen. We've built an Emergency Recovery system into Zen so that it's a simple process to get up and running again.

Connect a mini-USB cable from the PROG USB Port of the Cronus Zen to a computer with Windows installed (PC or MAC).
If the Zen Studio software still says 'Device Disconnected' even though you have connected your Cronus Zen to your computer, it is because your device hasn't been updated to the latest firmware, the mini-USB Cable is bad or the device is somehow corrupted and requires you to run the Emergency Recovery procedure.
If the Zen Studio software still says 'Device Connected But Not Responding', simply tap the reset button on the bottom of the Zen. You can also disconnect the mini-USB cable from the PROG USB Port and reconnect. If this still doesn't work you may need to Update the Firmware.

If you get a message saying Failed / Error when trying to program a script or GamePack, or if M&K settings are failing to save to your Zen, it is usually because the mini-USB cable is faulty, or your Zen Studio install has become corrupted and needs to have its temporary folder deleted so it can be freshly restored the next time you run Zen Studio.
The solution is to delete the CronusZen folder which is located here:
You can delete the folder manually or download and run the Scrub Zen Tool 👇 which will backup your CronusZen folder to C:\CronusZenBackup and then delete the source.

If you have problems downloading or opening Zen Studio it is because your .NET Framework drivers👈 are not up to date, or your Anti-Virus software has triggered a false positive due to the encryption algorithm we use. False positives usually happen with the Windows built in security tool “Windows Defender” which we recommend you disable (you can use the third party NODEFENDER tool to do it properly but you'd still need to at least disable Windows Defender temporarily to be able to run that). Do not worry about these false flags, our software is completely safe. To disable Windows Defender temporarily; you can simply do the following:
Click on Update & Security.
Click on Windows Defender.
Turn off the toggle switch for Real-time protection.
While Windows Defender doesn't specify how long you can disable real-time protection, "temporary" usually means until the next time you reboot your computer. BitDefender, Avast, McAfee, Norton etc can cause problems too. Again, do not worry about these false flags, our software is completely safe. You can temporarily disable the AV software then simply add zen_studio_latest.exe to the whitelist. Consult your security software documentation on how to do that.
🔎 Here are some helpful guides collected from the web 👉
Zen Studio is compatible with Windows 7, 8 and 10. However it can also work with macOS (Sierra 10.12 and above) which can easily run Windows 10 in a dual-boot configuration using tools such as Boot Camp and Parallels Desktop. If you don't own Windows, you can download a trial copy of Windows 10 here (click on the 'Download Tool Now' button and use the Media Creation Tool).

Windows 7 requires a driver fix. The file can be found on the Cronus Downloads Page.
All GamePacks are hosted online, so if your internet connection is bad, or your network or security software is blocking access, then you will not be able to use the GPC Library or GamePacks.
Each Zen GamePack has its own support community, so if you can't get a specific feature in a GamePack working, or don't understand how it works - create a post in the correct category of Zen GamePack Forums.

If you are trying to use a wireless Xbox One controller using Bluetooth on an Xbox One console, you will also need a licensed wired Auth controller connected to the A1 USB Port. This is because an Xbox One requires Authentication with an original controller in order to bypass security challenges and pass-thru controller outputs to the console.
Authentication over Bluetooth is not possible, so a second Xbox One controller has to be connected to the A1 USB Port👇
🔎 Find more detailed information about Xbox One Controllers👉 here:
If your Xbox One controller is regularly disconnecting from the Xbox One Wireless adapter, or won't connect at all, it's most likely the adapter is either not strong enough, not compatible with Zen, or faulty. The good news is that this is separate from the Cronus Zen device, so the issue can be easily fixed by replacing the Xbox One wireless adapter.
If you purchased the adapter from our store we will happily replace it with a brand new model.

If your DualShock 4 Bluetooth controllers have been paired to the Cronus Zen, but you now need to connect them back to the console and they are no longer working, it is because they have become unpaired from the console and you will need to run the pairing process again. On a PS4 this is done by connecting the controller to the console via micro-USB cable.

As there is no headset audio support over Bluetooth, Cronus Zen has a bypass feature that allows you to connect your headset directly to the Pass-Thru Auth Controller (see below image).
🔎 Find more detailed information about PS4 Controllers 👉 here:
As there is no headset audio support over Bluetooth, Cronus Zen has a bypass feature that allows you to connect your headset directly to the Pass-Thru Auth Controller (see above PS4 example).
This usually happens when a script is causing too much CPU load, interference with a wireless adapter, or sometimes it may happen if you are using the headset in a "crossover' scenario (PS4 controller on an Xbox One for example).
If the issue persists, try connecting your headset directly to an auth controller connected to the A1 USB Port. The Auth controller match the console you are using. If you are using a DualShock 4 controller, only the v2 model supports audio.
The headset must be connected directly to the sound card of the PC, not the controller.
You must connect the headset directly to the controller with the 3.5mm audio jack. The controller can then be paired wirelessly to the wireless adapter that is connected to the A3 USB Port of the Cronus Zen (see image below).
In the unlikelihood that your Cronus Zen error is still not resolved even after following all the Troubleshooting steps, then it's possible that your Zen has developed a hardware fault - but don't worry, you can return it to the original point of purchase to get it repaired or replaced under its warranty.
