http://bugs.winehq.org/show_bug.cgi?id=58345 --- Comment #6 from Bernhard Übelacker <bernhardu(a)mailbox.org> --- Created attachment 78815 --> http://bugs.winehq.org/attachment.cgi?id=78815 debugging notes and backtraces I think I found something, unfortunately MSISelectionTree_WndProc truncates the pointer of a newly created item. Therefore the attempts to add child items fail because the treeview does not find the item by the truncated pointer. Following merge request changes the type of the variable. With it also the 64-bit msiexec shows the product features. https://gitlab.winehq.org/wine/wine/-/merge_requests/8397 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
