Problem: "Download keeps failing" or "Corrupted archive."
Solution: Use a download manager. The ETAP installer is roughly 5–7 GB; poor connections often cause timeouts. Clear your browser cache or try a wired Ethernet connection.

Problem: "I cannot find version 21.0.1 on the portal."
Solution: Your maintenance plan may have expired. Contact ETAP support directly. Alternatively, the portal may default to the latest major version (e.g., 22.0). Check the "Archives" or "Patches" tab.

Problem: Antivirus deleted the license manager.
Solution: Restore the file from quarantine and add the entire C:\Program Files\ETAP 2101 folder to your antivirus exclusion list.
