I downloaded DOSbox v 0.6.3 and installed it succesfully.. Then downloaded the latest version of DOSboxFE ( a configuration tool for Dosbox, in linux).. configured the DOSbox for WC III. I removed the EMS support.
Then Started the DOSBox.. did the mountings, started the installation.. And i had to disable the sound, do to an error that it was returning due to a sound file..
Run the same process again, without the sound.. but i got e similar error, for a Dataflow file or something like that...
Now i have to take a break.. cause my eyes.....
