HELP!!

Having found one of the best DOS games ever made I am having trouble running it. I have downloaded it from Adandonia website. It works up until I go and do a misson and I get an unrecoverable error. I have Windows XP. I have used DOS Box but is says ''File not compatible with DOS'' Can anyone help me???
Thanks

That's the Windows version that is available on the site, running it with DOSBox is hopeless. The most common answer to this error that I just found out would be to make sure you did not install the game from within the archive (i.e. don't click on the setup.exe file in the archive thinking it's a setup to install the game).

Unzip the archive completely with the directories and everything to a single directory and run it from there.

I hope this answer works because a lot of random people seems to have problem running those Windows version and if this doesn't solve your problem I don't have an answer for you.
