 # Changelog
 
+## v1.0.4 – 2026-02-13
+- Windows CMD script now requires **installed 7-Zip (7z.exe)** for extraction.
+- Removed/disabled the portable `7zr.exe` path because it can fail to open `.procreate` ZIP archives reliably on some systems.
+- README updated to reflect the “installed 7-Zip only” requirement for the CMD script.

 ## v1.0.3 – 2026-02-13
 - Windows CMD script now uses 7-Zip (7z/7zr) instead of PowerShell for thumbnail extraction.

-The CMD script extracts thumbnails using **7-Zip** (recommended for better robustness than embedding long PowerShell one-liners in CMD).
+The CMD script extracts thumbnails using the **installed 7-Zip CLI (`7z.exe`)**.
 
-#### Requirements (choose one)
+Why installed 7-Zip only?
+- The small standalone `7zr.exe` can be blocked by security tools and/or fail to open `.procreate` ZIP archives reliably on some systems.
+- `7z.exe` (installed version) works consistently for this extraction method.
 
-**Option A: Portable (no install)**
-1. Download the **7-Zip console executable** (`7zr.exe`) from the 7-Zip download page https://www.7-zip.org/download.html 
-2. Put `7zr.exe` in the **same folder** as:
-   - your `.procreate` files
-   - the `.cmd` script you run
+#### Requirements
 
-**Option B: Install 7-Zip**
-1. Install 7-Zip using the Windows installer from https://www.7-zip.org/download.html
-2. The script will try these common locations automatically:
-   - `%ProgramFiles%\7-Zip\7z.exe`
-   - `%ProgramFiles(x86)%\7-Zip\7z.exe`
-3. (Optional) Add 7-Zip to your `PATH`.
+1. Install 7-Zip using the Windows installer from the 7-Zip download page.
+2. The script will find `7z.exe` in one of these ways:
+   - via `PATH` (if you’ve added it), or
+   - in common install paths:
+     - `%ProgramFiles%\7-Zip\7z.exe`
+     - `%ProgramFiles(x86)%\7-Zip\7z.exe`

 REM A .procreate file is a ZIP archive. The embedded preview is at:

 REM
-REM REQUIREMENTS (choose one):
+REM REQUIREMENTS (Windows 10/11):
+REM   - Install 7-Zip (recommended): https://www.7-zip.org/download.html
+REM     (Install the "7-Zip for Windows" package.)
 REM
-REM Option A (portable, no install):
-REM   1) Download 7zr.exe from 7-zip.org (console executable)
-REM      Put 7zr.exe in the SAME folder as:
-REM        - your .procreate files
-REM        - this .cmd script
-REM
-REM Option B (install 7-Zip):
-REM   1) Install 7-Zip (Windows installer)
-REM   2) This script will try common locations:
-REM        %ProgramFiles%\7-Zip\7z.exe
-REM        %ProgramFiles(x86)%\7-Zip\7z.exe
-REM      (or you can add 7-Zip to PATH)
+REM IMPORTANT:
+REM   - This script uses the installed 7-Zip CLI: 7z.exe
+REM   - The small "7zr.exe" (standalone) is NOT supported here because it
+REM     cannot open ZIP archives reliably for this use-case (it is mainly
+REM     for 7z archives), so .procreate extraction will fail.
 REM
 REM USAGE:
-REM   Place this script in the folder containing your .procreate files
-REM   then run:
-REM     extract-procreate-thumbnails-7zip.cmd
+REM   1) Copy this .cmd file into the folder that contains your .procreate files
+REM   2) Run it from Command Prompt (CMD):
+REM        extract-procreate-thumbnails.cmd
 REM
 REM OUTPUT:
 REM   file.procreate -> file.png
 REM   failures are logged to problems.log
+REM
+REM NOTES / LIMITATIONS:
+REM   - CMD can be fragile with special characters in filenames (e.g. &, ^, !).
+REM     If you have such filenames, prefer the PowerShell script.
