Unlock TradeStation ELD file

I have two TradeStation eld files which are source protected, with the primary code inside a dll. The two studies work fine on my old computer (32bit). The code will no longer work on my new computer (64bit). The programmer died 12 years ago so I am stuck. I need to get the two indicators working on my computer and eliminate the dll. I can send you the files and if you wish a VM file with the code working ( you will need Oracle VM VirtualBox). Thank you.
