The file dlusb-c120.exe (often referred to as dlusb_launcherC120.exe) is the proprietary driver and launcher for the Acer C120 Pico Projector. Option B: Manually update driver:
Because this projector is "plug-and-play" over USB, the executable is typically stored on a small internal flash partition within the projector itself rather than being a standard downloadable installer from Acer’s main support page. How to Access the File
Plug in the Projector: Connect the C120 to your laptop using the USB cable (ideally a USB 3.0 port for power and data).
Open File Explorer: The projector should appear as a new "Removable Storage" or "CD Drive" device in This PC.
Run the File: Open that drive and look for dlusb_launcherC120.exe. Double-clicking this file starts the driver installation and projection process. Troubleshooting Common Issues
If the file does not appear or fails to run, try these common fixes:

. Because this projector is powered and receives data entirely via USB, it relies on this specific executable to mirror your screen. Critical Troubleshooting Guide
If you are struggling to get the dlusb-c120.exe to run or the projector to display, follow these "deep-dive" fixes shared by the Acer Community:
Bypass "App Can't Run" Errors: On Windows 10 or 11, the launcher often fails due to compatibility. Right-click dlusb_launcherC120.exe, go to Properties > Compatibility, and set it to run in Windows 7 mode.
The "Two-Port" Power Rule: The C120 often comes with a USB Y-cable. Plug the main connector into a USB 2.0 port for data and the secondary (slave) connector into a USB 3.0 port for maximum power. If it doesn't get enough juice, the .exe will never trigger.
Antivirus Interference: Security software often flags this auto-run executable as a threat. You may need to manually add dlusb-c120.exe to your antivirus allowlist/exclusions.
Resolution Caps: The driver is designed for older standards. Ensure your laptop resolution is set to 1280x768 or lower before launching the file; higher resolutions can prevent the driver from initializing the external display.
Manual Install: If the "virtual CD drive" doesn't appear when you plug it in, check Devices and Printers in your Control Panel to see if it's listed as an "unspecified" device. You can often download the official driver package directly from the Acer Support Page.
