If you need to make a PB/DOS application install and run in all
versions of Windows, see PBDOSWIN.ZIP in PowerBASIC document
library http://www.powerbasic.com/files/pub/docs/.

Zip file contains PDF document: 38 pages of text, code, and
illustrations which you may freely use. Solves all the major
issues at a maximum cost of $49 (if you choose to license the
Astrum InstallWizard).
