Hola, estoy muy interesado en poder simular el puerto paralelo con proteus, que estoy comenzando a conocer, y me sale un error que no se su origen puesto que puse los archivos de libreria y modelo donde decia (carpeta de proteus).
Tambien copie el Inpout32.Dll y hwinterface.ocx al windows/system.
Tengo proteus 6.6 sp1 y winxp
aqui la imagen del error.

y el el log me tira lo siguiente:

Me llama mucho la atencion la linea que dice :
ERROR: [LPT1] DSIM model PORT.DLL failed to authorize - Product Key not found.
pero no se como podria solucionar estoy, agradeceria cualquier tipo de orientacion y sugerencia.
