Re^3: access 64bit registry from 32 bit Perl

in thread access 64bit registry from 32 bit Perl

goto C:\WINDOWS\SysWOW64 in explorer, double click on cmd.exe,

Microsoft Windows [Version 5.2.3790]

C:\WINDOWS\SysWOW64>cd ..

C:\WINDOWS>cd Sysnative

C:\WINDOWS\Sysnative>
[download]

Only 32 bit processes can see it. It doesn't exist in a 64 bit process. Server 2003 x64 used for above example (I did apply the MS patch to enable sysnative on server 2003 btw). If I try a normal (64 bit) cmd.exe I get

C:\WINDOWS>cd Sysnative
The system cannot find the path specified.

thanks ! The following did the magic for me : system("\"%systemroot%\\sysnative\\reg\" query HKLM\\software\\galil /s")	[reply]

Yes, you're right. I add the absolute path to my code and get what I want. The Sysnative only visible by 32bit cmd.exe. Thank you!	[reply]

Bulk88: I still got a problem if you can see it. the regedt32.exe seems must run using run as administrator in Win7. So it comes a problem when I want to run it quietly without any manual interference. What I can think is using runas before it. but runas didn't support password...I don't know how to do then...could u help me? or I had to create a new thread	[reply]

I don't use NT6, so UAC/etc I have no experience. There is Win32::AdminMisc, also see Windows runas command Runas using open Creating a process as a normal user without password (Linux 'su' for Windows 7?). runas.exe uses the C CreateProcessAsUser and/or CreateProcessWithLogonW internally, so try find a Perl module, that contains those 2 names in its XS code or its POD docs. Worst case use Win32::API, CreateProcessWithLogonW seems easiest to use since it doesn't have very many complicated structs/data types, see http://msdn.microsoft.com/en-us/library/windows/desktop/ms682431%28v=vs.85%29.aspx and Win32::API and CreateProcessWithLogonW. And start a new thread, this one has gone too deep in replys.	[reply]

You could always use psexec -? -accepteula /accepteula 1>NUL 2>NUL psexec.exe -d -l -u username -p password myfoo.bat `-d Don't wait for process to terminate (non-interactive). -l Run process as limited user (strips the Administrators grou +p and allows only privileges assigned to the Users group). On Windows Vista the process runs with Low Integrity.` [download]	[reply] [d/l]
