TechSmith Install & Auth

Overview

TechSmith products (Snagit, Camtasia) offer automation through the Snagit COM Server API (Windows) and Camtasia's command-line batch processing. No traditional API keys -- COM registration is the auth mechanism.

Prerequisites

• Windows OS (COM API is Windows-only)
• Snagit 2023+ or Camtasia 2023+ installed
• PowerShell 5.1+ or .NET SDK for COM interop

Instructions

Step 1: Verify Snagit COM Server Registration

# Check if Snagit COM server is registered
$snagit = New-Object -ComObject Snagit.ImageCapture
if ($snagit) { Write-Host "Snagit COM server registered successfully" }

Step 2: Re-register COM Server (if needed)

# Run as Administrator
$snagitPath = "C:\Program Files\TechSmith\Snagit 2025\Snagit32.exe"
& $snagitPath /register

Step 3: Python COM Interop

# pip install pywin32
import win32com.client

snagit = win32com.client.Dispatch("Snagit.ImageCapture")
print(f"Snagit version: Connected via COM")

Step 4: C# COM Interop

using SNAGITLib;

var capture = new ImageCaptureClass();
Console.WriteLine("Snagit COM initialized");

Step 5: Verify Camtasia CLI

# Camtasia batch producer
$camtasia = "C:\Program Files\TechSmith\Camtasia 2025\CamtasiaProducer.exe"
& $camtasia --help

Error Handling

Error	Cause	Solution
REGDB_E_CLASSNOTREG	COM not registered	Run Snagit32.exe /register as admin
Class not registered	Wrong bitness	Use 32-bit PowerShell for 32-bit Snagit
pywin32 not found	Missing package	pip install pywin32
Camtasia CLI not found	Not in PATH	Use full path to CamtasiaProducer.exe
