Games not launching from the launcher?

[Bandit Darville]

The Police Quest Collection launcher starts up no problem but when i click on any of the four games in said launcher, nothing happens. Trying to launch the games manually also does seemingly nothing. Any ideas? I have a feeling it's a DosBox problem because that isn't launching either; Have tried downloading the newest version as well but no dice. :(

I cannot get Police Quest 1 VGA to start. Are you having the same issue?
