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. dlusb-c120.exe

Developing a "feature" for this specific file or its environment typically involves addressing its main limitation: compatibility with modern operating systems like Windows 10 and 11. Recommended "Features" to Develop
If you are looking to improve or stabilize the functionality of this projector, focus on these areas: Compatibility Auto-Fixer:
The Issue: The original .exe was designed for Windows 7 and often fails on newer systems.
The Feature: Create a script or wrapper that automatically sets the file's properties to Windows 7 Compatibility Mode and Run as Administrator. Driverless "Plug-and-Play" Emulation:
The Issue: The device often shows up as an "Unknown Device" if the launcher doesn't trigger.
The Feature: Develop a background service that detects the specific hardware ID of the Acer C120 and forces the launch of dlusb-c120.exe without manual user intervention. Display Mirroring Optimization:
The Issue: Users frequently report lag or "App can't run on your PC" errors. You're interested in the story behind dlusb-c120
The Feature: Implement a lightweight display capture tool that pipes the screen data specifically to the USB port using the C120's proprietary protocol, bypassing the aging DisplayLink-based launcher. Troubleshooting Known Issues
If your "feature" is intended to fix a bug, here are the most common points of failure:
Virtual Drive Visibility: Ensure the computer recognizes the projector as a storage device first. If it doesn't, the .exe cannot be found.
Antivirus Interference: Many security programs flag this specific .exe because it attempts to "capture" the screen to project it. Whitelisting the file is often the first step in any functional enhancement.
