Hello,

well i looked into the matter. Some hours of nasty debugging (windows of
course) ...
First: don't try to fool around by patching IsDebuggerPresent() or
CheckRemoteDebuggerPresent().
The protector "probe" writes directly to PEB->teb() area to verify with API
returns to detect inconsistencies (hooks or fake value returns).

The showstopper why Securom 6.x, 7.x doesn't currently work under wine is due
to mismatching process heap structure layouts.
The protector accesses process heap structure members which do not exist in
wine or have other meanings.
The current layout is the choice made by wine developers losely based on
infamous Pietrek books.
To fix this issue not only the process heap structure layout need to be
adjusted but some parts of the process heap creation/init code need to be
rewritten too.

Regards
