Common Issues & Troubleshooting

⚠️ Windows: “Windows protected your PC”

Since Engauge is open-source software, it is not digitally signed by Microsoft. If you see this blue popup:
1. Click the small “More info” text.
2. Click the “Run anyway” button.

⚠️ Windows: “Missing VCRUNTIME140.dll”

This means your computer is missing the standard C++ libraries. You need to download and install the Visual C++ Redistributable (x64) from Microsoft’s official website.

Legacy Archives & Source Code

Looking for versions compatible with Windows XP/Vista, or want to build the software yourself? Access our legacy catalog and open-source repository.

Version / Type Year Best For… Download Link
Source Code (Latest) 2024+ • Developers & Linux Users
• Build v12.x from scratch 		GitHub Repository
v5.2 (Legacy) 2012 • Windows XP / Vista
• Very old hardware 		SourceForge v5.2
v4.1 (Legacy) 2009 • Windows 2000 / 98

ℹ️ Where are versions 6.0 – 11.0?
Intermediate versions were hosted on a now-defunct repository. If you are not on Windows XP, we strongly recommend using the Portable v12.1 (Section 1) which is the most feature-rich stable version available.

System Requirements

Engauge Digitizer is lightweight. However, since you are using the portable/archive versions, please ensure your system meets these dependencies.

Component Minimum Recommended
Operating System Windows 7, macOS 10.13, Linux Windows 10/11, macOS 12+ (Monterey+)
Architecture x86_64 (Intel 64-bit) Apple Silicon (via Rosetta 2 or MacPorts)
Native Windows x64
Memory (RAM) 2 GB RAM 4 GB+ (Essential for large maps)
⚠️ Critical Dependencies
(Windows Portable)		 Visual C++ Redistributable Most Windows 10/11 PCs have this pre-installed. If the app fails to start, install MSVC Runtime.
Display 1280 x 720 1920 x 1080 (For precise clicking)

💻 Apple Silicon (M1/M2/M3)

If you use the MacPorts method, the app runs natively (Fast).
If you use an older .dmg binary, macOS will ask to install Rosetta 2 to translate the Intel code. This works perfectly fine but requires that one-time setup.

🛡️ No Admin Rights? No Problem.

The Windows Portable Zip version does not require Administrator privileges to run. This is ideal for students or employees using restricted laboratory computers. Just extract and run.
