These tools compress the executable, hiding the RTTI and DFM resources inside an encrypted payload. When loaded into a decompiler, the binary will look empty or corrupted. You must unpack the binary (using automated tools or manual dynamic analysis in a debugger like x64dbg) before loading it into a Delphi decompiler.
Delphi 7 stores form data (windows, buttons, layouts) in a specific format called borland delphi 7 decompiler
