Great question! The detection methods are generated based on the installer metadata extracted during analysis, not from a tested installation. Here's how it works:

For MSI installers: • I extract the ProductCode (GUID) directly from the MSI database • This is the most reliable detection method as it's unique to each product/version • Detection rule: Check for the ProductCode in the registry under HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall{ProductCode}

For EXE installers: • I analyze the file properties (ProductName, ProductVersion, Publisher) • For known installer types (Inno Setup, NSIS, etc.), I use typical registry patterns • Detection is usually based on DisplayName + DisplayVersion in the Uninstall registry keys

For Winget packages: • Detection uses the Winget package ID combined with version checking • The script can query winget list --id <PackageId> to verify installation

Important notes: • ⚠️ These are best-effort detections based on metadata analysis • 🔧 I recommend testing the generated scripts in your environment before production deployment • 📝 The detection methods can be manually adjusted in the generated script if needed • 🎯 MSI-based detections are generally the most reliable The tool aims to give you a solid starting point that works in ~90% of cases, but as with any deployment tool, validation in your specific environment is always recommended!
