Keep custom user libraries in a separate, dedicated folder outside the main installation directory. This prevents your custom component footprints from being overwritten during software updates or patches.
Install the Visual C++ Redistributable for Visual Studio 2015-2022 (both x86 and x64 versions). Proteus 9.1 relies on these runtimes. proteus 91 full upd

Transfer your components to the PCB layout module. Component footprints will appear in your picker window alongside green rat's nest lines indicating electrical connections. Place high-frequency components and decoupling capacitors as close to their respective IC pins as possible. Use manual routing for critical paths (like power grids and high-speed data pairs) and let the autorouter handle the remaining general-purpose I/O traces.
