Instructions
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
