I've taken note that you want me to help with installing RegCool 1.347 for Mac.

Based on your provided text, it seems that you have a key for this specific software. I'll guide you through the installation process.

Since you're using a Mac with Apple silicon, please follow these steps:

1. Go to System Preferences > Software Update and make sure your Mac is running the latest version of macOS.

2. Click on the 'App Store' icon in the Dock or search for it in Spotlight.

3. Sign in with your Apple ID if prompted.

4. Search for RegCool 1.347 in the App Store search bar.

5. Click on the 'Get' button next to RegCool 1.347.

6. Wait for the download and installation process to complete.

7. Once installed, you can find RegCool 1.347 in your Applications folder or use Spotlight to search for it.

Please note that since the key is not a standard App Store code, I'm assuming it's a licensed copy. Make sure you have the correct license details ready before proceeding with the installation.

Additionally, if you're experiencing any issues during the installation process, please feel free to ask, and I'll do my best to assist you further.
