When installing Corel AfterShot Pro 2 to a Linux Ubuntu system, you might receive a “ia32-libs missing” message. In versions of Ubuntu prior to 13.04, ia32-libs was used to run 32-bit applications on 64-bit operating systems. Later versions of Ubuntu use MultiArch and do not require ia32-libs.
Reference for MultiArch: https://help.ubuntu.com/community/MultiArch
If the OS is requesting ia32-libs, see the following link for manual download and installation options:http://packages.ubuntu.com/search?suite=default§ion=all&arch=any&keywords=ia32-libs&searchon=names
