I've taken note of the key and text provided. The key is 'ExamDiff Pro 14.0.1.15 instal the new version for android' and the text appears to be a product description and feature list for ExamDiff Pro, a file comparison tool.

If you'd like to install the new version of ExamDiff Pro on your Android device, I can provide you with step-by-step instructions. However, please note that the key mentions 'instal' (with one 'l') which might be a typo. Assuming it's meant to say 'install', here are the general steps:

1. Go to the Google Play Store on your Android device.

2. Search for 'ExamDiff Pro' in the search bar.

3. Select the ExamDiff Pro app from the search results and click 'Install'.

4. Wait for the installation process to complete. This may take a few minutes, depending on your internet connection and device specifications.

5. Once installed, launch the ExamDiff Pro app and follow the prompts to register or log in to your account (if required).

Please note that it's recommended to uninstall any previous versions of ExamDiff Pro before installing the new version. Additionally, if you encounter any issues during installation or have questions about using the app, feel free to ask and I'll do my best to assist you.

Would you like me to provide more information on the features and benefits of ExamDiff Pro, or is there anything else I can help you with?
