Hi,
Here you can download HALion 4:
You can download an ISO image (disc image) here:
http://support.steinberg.de/ISOs/HALion_4_App_Cont_1.iso
http://support.steinberg.de/ISOs/HALion_4_Content_2.iso
Use any common burning software to create installation DVDs from the ISO images. On Mac OS X and Windows 8, ISO images can be opened as virtual drives directly by double-click. To be able to do so on older Windows releases, you need, for example, an utility as “WinCDEmu”.
All the Best,
