Inventory & Gap Analysis

Last Updated: February 13, 2026
Status: ✅ COMPLETE | All gaps closed | Ready for WiX development

Note: This document has been substantially updated based on actual analysis of the v3.60 installer and v7.0(patch) files (Jan 13-20), multi-OS testing (Feb 10), Win10 compatibility validation (Feb 13), and manual v11 installation success (Feb 13).

Why this matters

Your known constraint is explicit:

  • The current source appears behind the newest build.

  • We must determine whether the newest build can be patched after install (preferred) or whether we must reverse engineer + recreate (risk, delay).

This document defines what we must inventory and the decisions we must make by the end of P1/P2.

Key Discoveries:

  • (Jan 20, 2026): We successfully decompiled the installer, giving us full visibility into the installation logic.

  • (Feb 10, 2026): Multi-OS testing validated installer on XP, Vista, Win7 - all pass as Administrator.

  • (Feb 13, 2026): Win10 32-bit FULL STACK WORKING with AC2000 + CV auto-config script.

  • (Feb 13, 2026): Manual v11 installation RESOLVED - all files, registry, and auto-load working.

  • (Feb 13, 2026): P1 InstallShield sprint ABORTED (low ROI) - proceeding directly to WiX.

Conclusion: Combined with complete LSP source files in v7.0(patch), we have sufficient source to rebuild without reverse engineering. Gap analysis is COMPLETE.

  • csv.cui - Modern CUI menu format (AutoCAD 2006+)

  • SendTo.exe - Windows shell integration utility

  • wincss2000.exe - External utility

  • Font files, plot styles, project templates

Inventory checklist (deliverable: “Bill of Materials”)

1) Source tree inventory ✅ COMPLETED

  • ✅ Full file tree with hashes (SHA-256), sizes, timestamps

  • ✅ Identified:

    • ✅ user-facing commands / entry points (main.lsp, csvmenu.lsp)

    • ✅ library modules vs. “apps” (77 LSP files categorized)

    • ✅ config files and defaults (invar.lsp, project.dcl)

    • ✅ sample templates, blocks, title sheets (Project Files/, Fonts/, Plot Styles/)

Artifacts:

  • File inventory: v360_files.csv, v7.0_files.csv

  • Source comparison: source_comparison.txt

  • Diff analysis: diff_results.txt, diff_results_complete.txt

2) Build pipeline discovery (legacy) ✅ COMPLETED

  • ✅ How VLX was produced:

    • Tool: VLIDE (Visual LISP IDE) in AutoCAD

    • Source: .lsp files compiled to .fas, then packaged to .vlx

    • Note: Cannot decompile VLX → must recompile from LSP source

  • ✅ Dependencies identified:

    • CSV.ARX - C++ extension (binary, cannot recompile without source)

    • pcms.arx - C++ extension (binary, cannot recompile without source)

    • No COM registrations found

    • No DLL dependencies outside AutoCAD

  • ✅ Licensing: License.txt present, no runtime license checks in LSP

3) Runtime behavior inventory ✅ COMPLETE

  • ✅ Start-up hooks identified:

    • Menu autoload via csvmenu.lsp

    • main.lsp as application entry point

    • enable.lsp / fenable.lsp for feature toggling

  • ✅ Output destinations: Verified on Win10x32 VM (drawing operations + COM automation)

  • ✅ User workflow sequence: Demo validation complete (Feb 13)

  • ✅ COM automation: Working on XP/Vista/Win7/Win10x32; fails on Win10x64 (needs 64-bit AutoCAD)

  • ✅ Auto-config script: Configure-ConstructiVision.ps1 automates post-install setup

4) Parity gap analysis (newest build vs. recovered source) ✅ COMPLETE

Goal: determine whether we can “close the gap” without a rewrite.

Evidence gathered:

  • ✅ v3.60 install media: Fully analyzed

  • ✅ v7.0(patch) files: Fully inventoried

  • ✅ Working VM snapshots: XP, Vista, Win7, Win10x32, Win10x64

  • ✅ Behavioral comparison: Validated Feb 13 (full stack working on Win10x32)

  • ✅ v11 manual installation: RESOLVED - all 152 files, registry, auto-load working

Final Assessment: ALL GAPS CLOSED

Gap Type

Status

Notes

Installer

✅ BYPASSED

P1 sprint aborted; WiX development NOW ACTIVE

LSP Source

✅ COMPLETE

All 77 files available, validated

VLX Binary

✅ VALIDATED

Existing VLX works on Win10x32 (no recompilation needed)

ARX Binaries

✅ NON-CRITICAL

csv.arx fails (Bug 4) but CV works without it

Menu Files

✅ COMPLETE

All formats available + auto-load via Startup Suite

COM Automation

✅ VALIDATED

Works on 32-bit Windows; 64-bit needs modern AutoCAD

Critical Findings

Finding 1: Installer Successfully Decompiled ✅ (P1 Sprint ABORTED)

Tool: isDcc v1.22 (Luca Borsato)
Result: setup.ins → setup.rul (4,163 lines of InstallScript)

Bugs Identified in Installer:

  1. AutoCAD Detection Bug - Uses file rename test (_acad.exe → acad.exe) which fails under UAC

  2. Menu Registration Bug - Hardcodes <<Unnamed Profile>> instead of detecting active profile

  3. Windows Vista+ Incompatibility - 95%+ failure rate on modern Windows

Resolution (Feb 13): P1 InstallShield sprint ABORTED — .rul recompilation has low ROI. Proceeding directly to WiX installer. Manual installation + auto-config script provides identical result with less risk.

Finding 2: VLX Works Without Recompilation ✅

Issue: CSV.VLX is compiled Visual LISP, no reliable decompiler exists
Original Plan: Recompile from LSP source files using VLIDE
Feb 13 Finding: Existing VLX files work perfectly on Win10x32 with AutoCAD 2000
Status: ✅ VALIDATED - No recompilation needed for 32-bit platforms Future: VLX recompilation may be needed for 64-bit AutoCAD (Week 12)

Finding 3: ARX Files Are Non-Critical ✅

Issue: CSV.ARX and pcms.arx are compiled C++ extensions
Problem: Cannot recompile without original C++ source code
Status: C++ source NOT found in current inventory

Feb 13 Resolution:

  • ❌ csv.arx fails to load (Bug 4) - but CV works without it

  • ✅ All core CV functionality operates normally

  • ✅ ARX dependency is NOT critical to CV operation

Decision: Accept ARX as non-functional. CV works without it. Lower priority than WiX development.

Finding 4: CUI File Extends Compatibility ✅

Discovery: csv.cui file present alongside classic menu files
Benefit: Supports AutoCAD 2006+ modern menu format
Status: May reduce menu migration work for modern AutoCAD

Parity Decision Gate (end of P1 / early P2)

Gate question

Can we reproduce the newest build outputs using recovered source + patch strategy?

Final Assessment (Feb 13, 2026): YES ✅ GATE PASSED

Component

Reproducible?

Status (Feb 13)

Installer

✅ BYPASSED

P1 sprint aborted → WiX development starting

LSP Logic

✅ VALIDATED

All 77 source files present and working
