After the files are extracted, navigate to the folder created on the hard drive. Locate and execute the
setup.exe file to start the installation. The DAC8775 software installer file then opens to begin the
installation process.

After the installation process initializes, the user is given a choice of selecting the installation directory,
usually defaulting to C:\Program Files(x86)\DAC8775EVM\ and C:\Program Files(x86)\National
Instruments\.

Figure 9. DAC8775EVM Install Path

After selecting the installation directory, two license agreements are presented that must be accepted.

Figure 10. DAC8775EVM Software License Agreements

After accepting the Texas Instruments and National Instruments license agreements, the progress bar
opens and shows the installation of the software. Once the installation process is completed, click Finish.
