PredatorSense App Missing / Not Installing on PH315-52 (Service Only Installed)

Hi all,

I’m using a Predator Helios 300 (PH315-52) running Windows 11 Home, and recently I’ve run into a frustrating issue with PredatorSense.

It was working perfectly for a long time, but suddenly the app stopped opening. I tried reinstalling it, but now only the PredatorSense Service installs — the app UI itself is missing, and there’s no desktop shortcut or .exe in the expected folder (C:\Program Files\Acer\PredatorSense). I’ve tested every version available on the official Acer support page for my model, including older ones.

Here’s what I’ve tried so far:

  • Full reinstall of PredatorSense (several versions)
  • Manual cleanup of all leftover folders and registry entries
  • Installed all chipset/MEI/ACPI drivers beforehand
  • Disabled Virtualization-Based Security (VBS)
  • Tried compatibility mode (even forced Windows 10 mode through registry)
  • Full Windows 11 reset and clean install

I also used HWiNFO and FanControl to check for EC/fan access, but no fan sensors or RPM values are visible — meaning third-party tools can’t control the fans either. I believe fan control is fully locked behind PredatorSense.

At this point, I'm wondering:

  • Is there a working version of PredatorSense for PH315-52 on Windows 11?
  • Has a recent Windows update or firmware change affected compatibility?
  • Can Acer support provide a direct working installer, or is there a known workaround?

Thanks
