Trying to install Anvil Studio in WINE version 0.9.39 on Gentoo Linux x86_64, I get the error message

Run-time Error '429': ActiveX component can't create object

Anvil Studio is a freeware MIDI sequencer. It has a few HTML help files and can check for/download updates for itself (which is what I suspect ActiveX is used for...). Am I missing something Anvil Studio needs in order to install? Is this an issue of a 64-bit OS playing host to a 32-bit application, despite having a multilib build of Gentoo?
