Installing Cadence tools can sometimes be tricky. Here are specific tips for the 17.4 Viewer:

Running as Admin: Right-click setup.exe and select "Run as Administrator."
Installation Command: The installer will ask for a command. For the Free Viewer, you typically do not need a license file setup. Just proceed with the "Product Installation."
Work Directory: During setup, it will ask for a "Working Directory." Keep the default or set it to a folder you have full read/write permissions for (e.g., C:\Cadence\SPB_17.4).

🆘 If You Still Can’t Find 17.4

Cadence periodically removes old versions from public download. Your options:

Contact Cadence support – if you have a customer number or are a student, they may give legacy access
Use newer free viewer (e.g., 22.1) – it still opens 17.4 board files
Use Altium or KiCad (free) – but they may not fully support Allegro proprietary formats
