I have attempted to try and install/play SimTower through DOS Box. Here are my stats, errors and other bits of info. YES I have read the README, 60 second Guide, and Installation Tips and Hints.

DOS Box v. 0.73
Windows 7 x64 Professional
Gigabyte MAS motherboard
Athlon X2 Processor

*Drive G is an external HDD

*Drive X is a virtual CD-Rom via Power ISO w/ SimTower mounted on it (did attempt to do this without a virtual drive to the same error)

*SimTower was downloaded from [DON'T DO THAT]

Command List
1. mount C "G:\DOS Box"
2. mount D "X:\" -t cdrom
3. D:
4. dir /w
5. setup.exe
6. simtower.exe

You can see the error in the screenshot "This program requires Microsoft Windows", and when I enter in command #6 it just freezes as you see in the screenshot. Any help would be nice, thank you.
