--- Comment #4 from Jeff D. Hanson jhansonxi@gmail.com --- After additional testing, the 32-bit installer (…/Setup.exe, …/Setup/Setup.msi) on Wine 1.8 only needs:
winetricks -q msxml3 win7
This allows the EULA to be displayed and the dialogs to function. It still errors after a time, independently of the installer progress. The faster you click through the steps, the further it gets before page faulting from mshtml. Installing IE8 (as for the downloader pspx8.0_32bit.exe) doesn't seem to affect the installer crash.
