Turtles Lite for Windows
- No installation required. Just extract the zip file and place it in any folder (e.g. Desktop).
- You can also place it in a shared folder and run it from multiple PCs.
- Please review the LICENSE and README included in the downloaded file before use.
Use on a Windows PC (recommended)
Note (First Launch):
If a security warning appears on first launch, this is a standard Windows security feature for apps from unknown publishers.
To run the app:
1. Click "More info"
2. Click "Run anyway"
If it does not start, try this version instead.
This version works better in environments where writing to the C drive is restricted (such as school or company PCs).
