I am tryin to bcd to binary converter. I want to just try 74184 converter but it does not work. How can I fix it?

 

Welcome to AAC!

Proteus can't simulate 74184 or 74185. That has been tried often enough by people posting on AAC that even us non-Proteus users are aware of the limitation.

The workaround has been to use a programmable memory with the conversion programmed.

Which program should I use?

You can still use Proteus. Just program the LUT in an EPROM. Here's an example for implementing 74185:
