7 Decompiler | Borland Delphi

Run the EXE in x64dbg (with Delphi helper scripts). Set breakpoints on known RTL functions (System::LStrCmp, TControl::Click). Trace the logic live. This gives you execution flow, but not static source code.

A decompiler exploits these to:

Delphi 7 IDE is obsolete and won't run well on Windows 11. Open your decompiled .dpr and .pas files in Lazarus (Free Pascal). The LCL is mostly compatible with Delphi 7's VCL. Fix resource differences (.dfm vs .lfm). borland delphi 7 decompiler

Decompiling Borland Delphi 7 executables is possible and often yields useful results, especially for recovering forms and event handler structures. Tools like IDR provide the best automated reconstruction, but full decompilation to exact original Pascal is impossible due to lossy compilation. The recovered output is a functionally equivalent but stylistically different version, requiring manual refinement. Delphi 7 IDE is obsolete and won't run well on Windows 11

For modern Delphi versions (10.x, 11.x, 12.x), RTTI has expanded, but decompilation remains fundamentally limited compared to managed runtimes.

Decompiled code is not instantly compilable. You must:
