Looking for utility to patch MSVC11+ EXE to run under XP (Developers)

Hi,
maybe you are aware with this issue, I met this today when running some MSVC13 binary (ELA ETER for RFID). I found the solution
https://tedwvc.wordpress.com/tag/windows-xp-sp3/
using EDITBIN.EXE that is a part of older MSVC. It also depends on LINK.EXE and MSPDB80.DLL. I rememember that I visited some personal's website where was offered a freeware patching utility to do the same without need a MSVC depencies but I cannot remember where and Google doesn't helping me much. Does somebody knows about it?

I wrote a small EDITBIN replacement myself with TCC (so it links to MSVCRT.DLL only).
http://roy.orz.hm/gpc/files1.rt/pehdr.zip

Usage: pehdr-lite <PE-file> [+|-dll] [+|-win] [+|-con] [-osver <number.number>] [-subsysver <number.number>]

+dll sets IMAGE_FILE_DLL and -dll unset it.
+win/-con changes Subsystem flag to IMAGE_SUBSYSTEM_WINDOWS_GUI
-win/+con changes Subsystem flag to IMAGE_SUBSYSTEM_WINDOWS_CUI

I don't need to explain -osver and -subsysver, right? ;-)

Hi there!
I use HIEW editor for this purpose.
( http://dml.compkaluga.ru/forum/index.php?s=89cdcd8...e2d8da&act=attach&type=post&id=1456 )
Press F8, then F3 and change OS, Image and Subsystem versions.
You could also recalculate checksum, since header content changed.
It is strictly needed for drivers (*.SYS files) - with bad checksum driver will be refused to run.
Press F3 under Checksum field and it will be recalculated.
Press F9 to save.

OK, thanks. Does your tool recalc the checksum? Editbin does.
EDIT: Yes as I can see in source there's code for this
/* recalculate PE checksum */
