--- Comment #4 from Nikolay Sivov bunglehead@gmail.com --- Hi, Lorenzo.
Thanks for the report and bisecting. This is already fixed in git, commit 0de689f41560208bbc14fb1a6b9f7dfe154326c1. Please retest with latest wine-git.
Relevant log part is:

The issue is that redirection is applied but implementation module is not loaded yet -> class is not registered -> window creation fails. In case of this installer failure to create dialog control most likely is fatal.
