Where the FAQ entry at http://www.network54.com/Forum/171757/message/1204454477/QBasic+in+Vista+or+64+bit+CPU+environment expects you to already have a copy of the QBasic/QuickBASIC program ready to use, this entry serves to explain how to install QuickBASIC if you have directories containing the files on the installation disks.
First of all, you need DOSBox. If you don't have it, you can download it from the DOSBox website located at http://www.dosbox.com
Assuming you already have the installation files, ensure they're all in a single directory (e.g. qbsetup/DISK1 contains ALL of the setup files). If you don't wish to do this, a bit more work is involved, but it is still relatively easy. In that case, please refer to http://www.network54.com/Forum/171757/message/1298828356/Installing+QuickBASIC+4.5+and+PDS+7.1+in+DOSBox+%28more+involved+method%29
Now in DOSBox, mount the parent directory of the target installation directory as your C: drive. For example, if you're installing QuickBASIC 4.5 to K:\dosprogs\QB45, you would use this command:
MOUNT C K:\dosprogs
Next, you need to mount the disk directory as the A: floppy drive. The following example assumes you are using DISK1 as the directory on your actual computer that contains every file for installation:
MOUNT A K:\dosprogs\qbsetup\DISK1
Now change to the A: directory in DOSBox and verify that you're in the correct directory:
DIR /W SETUP.EXE
If you don't see "File SETUP.EXE not found", then all is well.
Now type "SETUP.EXE" at the prompt, go through the menus and install to C:\QB45 (remember that it is K:\dosprogs\QB45 on your actual computer) or whatever directory you choose. It will ask for DISK2, DISK3, etc. Just hit the Enter key since it is all in a single directory.
You're finished! Congratulations on installing your selected version of QuickBASIC! :)
