Paquet Builder 2026.1 — What's Updated
Paquet Builder 2026.1 is out. This is a maintenance release for the 2026 line that resolves two regressions from 2026.0 and adds a couple of small runtime improvements.
Fixes from 2026.0
Native /LCID and /s Command-Line Switches
Two switches that previously required custom action templates are now parsed directly by the installer and uninstaller runtime:
Pre-Compile Component Validation
When a shortcut or registry entry references a component that doesn't exist (typo, renamed, or deleted), the IDE now reports the full list of bad references before code generation starts — instead of several minutes into the build.
Richer Runtime Crash Diagnostics
When an installer hits an unexpected exception, the error dialog now includes the exception code (e.g.

Paquet Builder 2026.1 is out. This is a maintenance release for the 2026 line that resolves two regressions from 2026.0 and adds a couple of small runtime improvements.
Fixes from 2026.0
- Multi-volume extraction returning
error -5 (can't open archive)— resolved. The archive chain now opens reliably across all volume sizes. - Sporadic Access Violation in 64-bit installers, typically at the tail end of installation when writing uninstall entries or component registry values — resolved. The runtime write paths are covered by an additional hardening pass.
Native /LCID and /s Command-Line Switches
Two switches that previously required custom action templates are now parsed directly by the installer and uninstaller runtime:
/LCID <num>selects a project language at launch directly by LCID. Multi-language projects no longer need thelanguage-from-command-line.xmlcustom action template./sand/silentare now parsed with exact token matching — no more substring false positives from arguments that happen to containsorsilent.
/s invocations in SCCM, Intune, PowerShell, or Group Policy scripts.Pre-Compile Component Validation
When a shortcut or registry entry references a component that doesn't exist (typo, renamed, or deleted), the IDE now reports the full list of bad references before code generation starts — instead of several minutes into the build.
Richer Runtime Crash Diagnostics
When an installer hits an unexpected exception, the error dialog now includes the exception code (e.g.
0xC0000005), the resolved fault address with module and offset, and a stack trace of the calling frames. Easier to triage field reports without attaching a debugger.Also in 2026.1
- New "Don't Show Again" button on the Additional Packages startup dialog.
- Fixed empty "Available Scripts" dropdown in the Call C Function custom action editor.
- Fixed hyperlinks in installer screens (License Agreement, WebView2, Markdown content) opening a blank Edge window under UAC Over-The-Shoulder elevation.
