Note: The "ProgramData" folder is usually hidden by Windows. Make sure to enable "Show hidden files" in your file explorer. Copy both the .LIB and .IDX files that you extracted. Paste them directly into the Proteus LIBRARY folder. Restart Proteus If you have Proteus open, close and reopen it.
If no data transfers, double-check:
Need the HT12E and HT12D Proteus library file download? This guide provides safe download links, step-by-step installation for Proteus 8/9, and a test circuit with 4-channel RF simulation. Ht12e And Ht12d Proteus Library File Download

To test if your Encoder and Decoder logic works: Paste them directly into the Proteus LIBRARY folder
In real life, you place an RF Transmitter (ASK/FSK) between HT12E and HT12D. In Proteus, dedicated RF modules (like the cheap 433MHz ones) often do not simulate behavior correctly or require complex analog modeling.
