Download and extract QuickBASIC 4.5 into a new subdirectory: C:\oldDOS\QB45
Your directory structure should now look like this (click images to enlarge):
[Fig. 1.1 - 1.3: Directories]
Once DOSBox has been launched, the welcome screen should appear as shown in Fig. 2.1.
Next, the QuickBASIC directory has to be connected to DOSBox using the MOUNT command
(don't forget to hit [ENTER] at the end of each line):

Finally, we need to launch QuickBasic 4.5 (which is the QB.EXE File)
To do this, we only need to type in qb and confirm with
