Bug ID: 57892 Summary: x86(32bit) exe's wrong registry redirect Product: Wine Version: 10.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: advapi32 Assignee: wine-bugs@winehq.org Reporter: axis6404@proton.me Distribution: ---
When x86(32bit) exe is executed from 64bitOS, the registry is redirected to wow6432node. Some cases are redirecting when they should not.
I have created a simple 10 line program as a test case, attached in 7z with the exe.
Description of the exe: Create HKEY_CURRENT_USER\software\wineTestRedirect.
Windows 8.1 (x64): Create HKEY_CURRENT_USER\software\wineTestRedirect.
wine (x64 debian): Create HKEY_CURRENT_USER\software\Wow6432Node\wineTestRedirect
How to fix: Do not redirect to HKEY_CURRENT_USER\Software* (and other special locations). A detailed list is available on MSDN. https://learn.microsoft.com/ja-jp/windows/win32/winprog64/shared-registry-ke...

And a bunch of other 32-bit exe's.

--- Comment #4 from Maotong Zhang zmtong1988@gmail.com --- I test this wineWOW6432node.exe on wine-10.3 , WINEARCH=win64, it doesn't generate a registration entry for 'HKEY_CURRENT_USER\software\Wow6432Node\wineTestRedirect'

--- Comment #5 from axis6404@proton.me --- The bug is not reproduced by WINEPREFIX; it is always reproduced by wine-devel10.3 in the .winedmm environment created on 2025/02/19. I will check how to reproduce it now.

wine version ?
My WINEPREFIX is a mix of versions with and without Wow6432Node. When this bug is fixed, wine users will have to port the data manually with regedit or give up setting below Wow6432Node.

Ok, Problem reproduce! There are projects in Wow6432Node, will not be created during the creation process Me analyze it

Can you test this patch? The patch has disabled Wow6432Node mapping and see if it will affect your program. In this way, a 64 bit system runs 32-bit applications without executing Wow6432Node mapping redirection. I always feel that this violates the Wow6432Node mapping and may require better methods to implement.

--- Comment #10 from axis6404@proton.me --- I did some testing of HKEY_CURRENT_USER\software only. Looks like the bug is fixed to me.

I did additional testing of the patch. I found one problem. Specifying KEY_WOW64_32KEY or RRF_SUBKEY_WOW6432KEY in PE64 exe causes wrong redirection I attach a small test case.
