Why WIS & EPC Remain Indispensable
Saab WIS (Workshop Information System) and Saab EPC (Electronic Parts Catalog) have been the backbone of accurate diagnosis and repair since Saab’s dealer days.
WIS contains Saab’s complete repair procedures, torque specifications, wiring diagrams, and diagnostic workflows. EPC provides VIN-specific part numbers, exploded diagrams, and supersession info—critical for ordering the right part the first time.
Originally designed for Windows XP 32-bit, these tools have been adapted by the Saab community to run on modern 64-bit systems, making them accessible to owners and independent garages alike.

Installing WIS & EPC on Modern Windows
The adapted versions work on Windows Vista, 7, 8, 10, and 11 (32 & 64-bit), but require a few setup considerations:
- Mount the ISO files using Windows’ built-in tool or WinCDEmu.
- Run installers as Administrator to register database components.
- Change languages (14 available) without restarting.
