Well, i run the installer CD under DOSBOX, but then the characters cant be displayed properly, instead thing like "Augmenter FILES=XX de config.sys (arrow right) OUVRE, OPTLANG.AID (arrow left)"
"PAS DE FENETRE EN COURS (arrow right) FERME (arrow left)"
Then the initial screen of the installer displays everything properly, but when i attempt to make a selection, the icons and the characters dissapear, and then another things like "CHAMP INCONNU (arrow right) AFFICHE, DISQUE=Unidad de instalacion: (arrow left)"

Note than the (arrow right, left) is actually an simbol, but i dont know how to transcribe it here. Also the language of my DOSBOX is Spanish

Here are the information about my PC

My motherboard is an Intel Desktop Board D915PGN, my processor is an Intel Pentium 4 3.00 GHz, 1.50 GB RAM, my video board is an NVIDIA GeForce 6200 Turbo cache 256 MB http://www.nvidia.com/page/geforce6200_pci, sound board i dont know how i can find that, i use Windows XP 32 bits, The name of the Game is "Call of Cthulhu: Shadow Of The Comet" http://en.wikipedia.org/wiki/Shadow_of_the_Comet
