Protel was the predecessor to the modern Altium Designer software suite.
Many industrial machines, medical devices, and military equipment built in 2000-2005 have PCBs designed in Protel 99 SE / Advanced PCB 2.8. Companies cannot simply "upconvert" these 20-year-old proprietary files to Altium Designer without significant risk of layer corruption or netlist errors. Engineers need a native copy of version 2.8 to open, edit, and generate Gerbers for legacy board revisions.
KiCad now includes a protel2kicad Python script. It converts .PCB (Advanced PCB 2.8 binary) files to KiCad format with about 80% layer fidelity. Protel Advanced Pcb 2.8 Download 2021
If you manage to find a legitimate copy of version 2.8, here is what you can expect:
| Feature | Capability | | :--- | :--- | | Maximum Layers | 32 signal layers + 16 internal planes | | Resolution | 1 nanometer (1nm) internal database | | Routing Grid | User-definable from 1mil to 1000mil | | Component Library | Over 15,000 footprint/components via integrated libraries | | Output Formats | Gerber RS-274X, Excellon NC Drill, DXF | | Design Rule Check (DRC) | Clearance, width, short-circuit, & unrouted net checks | | 3D View | Basic 3D preview (wireframe only) | | Operating System | Windows 95, 98, NT 4.0, 2000, XP (32-bit) | Protel was the predecessor to the modern Altium
One standout feature was the "Batch DRC" — users could run a complete electrical rules check on a 1000+ pad board in under 10 seconds on modest hardware.

Do not download Protel Advanced PCB 2.8 from random websites. Instead:
While "Protel Advanced PCB 2.8" remains a legendary tool in the history of electronics design, seeking a download in 2021 is highly discouraged for active design work. The combination of OS incompatibility, lack of driver support, and security risks outweigh the benefits. Users should migrate legacy projects to KiCad or Altium Designer to ensure future viability and file access. While "Protel Advanced PCB 2
