Now drag that folder, with the left mouse button, and drop it over DOSBox's shortcut, DOSBox will run and mount that folder as C:\. Then mount your CD drive, entering in DOSBox's command prompt «mount d "X:\" -t cdrom», where X is your CD drive's letter. Then run the installer from the command line. When you're asked for the installation path, leave "c:\kom".
