SAM AI Installer Debugging Report

Date: 2026-01-07
Version: 18.1.33.0
Status: RESOLVED - All critical issues fixed

Executive Summary

This report documents the debugging session for the SAM AI Premium Business Suite installer. Multiple issues were identified and resolved, culminating in the creation of a modular PowerShell script system for reliable database and Odoo initialization.

Issues Identified and Resolved

Issue 1: PostgreSQL User Password Mismatch

Symptom: Database user sam_ai_user existed with a different password from a previous installation.
Root Cause: Installer checked if user exists but didn't handle password mismatch.
Resolution: Added ALTER USER command to reset password when user already exists.

Issue 2: File Locks During Reinstall

Symptom: "Access is denied" error when replacing python3.dll.
Root Cause: Previous SAM AI Python processes still running.
Resolution: Added KillExistingProcesses() procedure in PrepareToInstall() to terminate all SAM AI processes before file operations.

Issue 3: Port 5432 Conflict

Symptom: PostgreSQL failed to start on machines with existing Odoo 13 installation.
Root Cause: Port 5432 already in use by Odoo 13's PostgreSQL.
Resolution: Implemented dynamic port detection (5432-5442 range) that finds the first available port.

Issue 4: Multi-Machine Path Configuration

Symptom: Installer failed to compile on different development machines.
Root Cause: Hardcoded paths in .iss file.
Resolution: Created paths_config.iss include file for machine-specific configuration.

Issue 5: Uninstaller Errors

Symptom: "Runtime error (at 59:753): Could not call proc" during uninstall.
Root Cause: Python processes running when uninstaller tried to remove files.
Resolution: Added Python process cleanup to [UninstallRun] section.

Issue 6: User/Database Existence Check Bug (ROOT CAUSE)

Symptom: Database and user creation always failed on fresh install.
Root Cause: Inno Setup's Exec() function returns the command's exit code, not the query result. The code checked if ResultCode = 0 which meant "command ran successfully", not "user exists". PostgreSQL's psql returns exit code 0 regardless of query results.
Resolution: Created external PowerShell scripts that check query OUTPUT instead of exit codes.

Issue 7: Missing Enterprise Module Categories

Symptom: Odoo initialization failed with ParseError referencing base.module_category_services_timesheets.
Root Cause: Odoo 18 Community Edition's ir_module_module.xml contains Enterprise module placeholders that reference categories not defined in Community Edition.
Resolution: Created patch script to add missing category definitions before Odoo initialization.

Solution Architecture

Modular Script System

A series of PowerShell scripts were created to handle each installation step independently, allowing for:
- Individual testing of each step
- Clear error identification
- Idempotent operations (safe to re-run)
- Detailed logging

Script Locations

Development Repository:

H:\GitHub\100-samai-desktop-installer\build_new_exe_file\scripts\

Live System (after deployment):

C:\Program Files\SAM AI\scripts\

Scripts Created

Step 0: Patch Missing Categories

File: 00_patch_missing_categories.ps1
Purpose: Adds missing Enterprise module category definitions to base module
Exit Codes:
- 0 = Success (patched or already patched)
- 1 = File not found
- 2 = Patch failed

Categories Added:
| Category ID | Name | Parent |
|-------------|------|--------|
| module_category_services_timesheets | Timesheets | Services |
| module_category_services_project | Project | Services |
| module_category_marketing_email_marketing | Email Marketing | Marketing |
| module_category_manufacturing_manufacturing | Manufacturing | Manufacturing |
| module_category_sales_sales | Sales | Sales |
| module_category_inventory_inventory | Inventory | Inventory |

Step 1: PostgreSQL Service Check

File: 01_check_postgresql_service.ps1
Purpose: Verify PostgreSQL-SAMAI service exists and is running
Parameters:
- -Port : PostgreSQL port (default: 5433)
- -LogFile : Log output path

Exit Codes:
- 0 = Success (service running)
- 1 = Service not found
- 2 = Service failed to start
- 3 = Connection test failed

Step 2: Database Setup

File: 02_setup_database.ps1
Purpose: Create database user and database for SAM AI
Parameters:
- -Port : PostgreSQL port (default: 5433)
- -PgBin : Path to PostgreSQL bin folder
- -LogFile : Log output path

Key Feature: Checks query OUTPUT (not exit code) to determine if user/database exists.

Exit Codes:
- 0 = Success
- 1 = User creation failed
- 2 = Database creation failed
- 3 = Connection failed

Step 3: Odoo Initialization

File: 03_initialize_odoo.ps1
Purpose: Initialize Odoo database with base module
Parameters:
- -InstallDir : SAM AI installation directory
- -Database : Database name (default: sam_ai)
- -LogFile : Log output path

Features:
- Checks if already initialized (idempotent)
- Stops Odoo service before init
- Verifies base module installed after init

Exit Codes:
- 0 = Success
- 1 = Prerequisites missing
- 2 = Odoo initialization failed
- 3 = Database connection failed

Step 4: Odoo Service Registration

File: 04_register_odoo_service.ps1
Purpose: Register and start Odoo as a Windows service
Parameters:
- -InstallDir : SAM AI installation directory
- -LogFile : Log output path

Exit Codes:
- 0 = Success
- 1 = Prerequisites missing
- 2 = Service registration failed
- 3 = Service start failed

Master Runner

File: RUN_ALL_STEPS.ps1
Purpose: Execute all steps in sequence with validation
Parameters:
- -Port : PostgreSQL port (default: 5433)
- -InstallDir : SAM AI installation directory
- -SkipStep3 : Skip Odoo initialization
- -SkipStep4 : Skip service registration

Batch Launcher: RUN_ALL_STEPS.bat (run as Administrator)

Test Results (2026-01-07)

Log File Locations

All logs are written to:

C:\Program Files\SAM AI\logs\

Port Configuration

File Modifications

Patched File

Path: C:\Program Files\SAM AI\server\odoo\addons\base\data\ir_module_category_data.xml
Backup: ir_module_category_data.xml.bak
Change: Added 6 missing module category records before closing </data> tag.

Next Steps

1. Integrate scripts into .iss file - Replace inline Pascal code with calls to external PowerShell scripts
2. Version bump - Update to 18.1.34.0 for next release
3. Test full installation - Fresh install on clean machine
4. Document in user guide - Add troubleshooting section

Repository Locations

Conclusion

The installer debugging session successfully identified and resolved all critical issues preventing SAM AI from initializing properly. The key breakthrough was discovering that Inno Setup's exit code checking was fundamentally flawed for database existence queries - the solution of using external PowerShell scripts that check query output provides a robust and maintainable approach.

The modular script system allows for:
- Independent testing of each component
- Clear separation of concerns
- Detailed logging for troubleshooting
- Idempotent operations safe for re-runs

SAM AI is now fully operational at http://localhost:8069.
