You want me to install the new PCDJ DEX 3.20.7, correct?

Before we begin, I'd like to clarify a few things. It seems that you have a file named 'PCDJ LYRX 1.10.2' which is not the software you're looking for (PCDJ DEX 3.20.7). Additionally, there's no specific download link provided.

However, I can help you find the installation package for PCDJ DEX 3.20.7. After researching, I found that PCDJ offers a free trial version of their software on their official website. You can visit their website and sign up for an account to access the free trial download.

Once you've downloaded the file, you can follow these steps to install PCDJ DEX 3.20.7:

1. Run the installer (it should be a `.exe` file) and follow the prompts.

2. Choose the installation directory and make sure it's a location that has enough free space.

3. The software will take some time to download and install, so please be patient.

Please note that the full version of PCDJ DEX 3 is not available for free. You may need to purchase a license or subscription to access all its features.

If you have any further questions or concerns, feel free to ask!
