I need to edit some values for a specific program of mine which is installed in C:\Program Files (x86), but I only have access to the HKEY_LOCAL_MACHINE\SOFTWARE for x64 bit applications. How would I have access to the 32 bit programs in the registry? I would normally access the registry using regedit.exe.

Any help appreciated.

Help please!

Don't understand, Where are these registries and why can't you use regedit? Are the registries in the same installation and same partition?

I am able to use regedit.exe and regedt32.exe

Perhaps it's something new for Vista x64 or all Microsoft x64 bit platforms, but navigating the registry is quite different (in the sense that I can't find what I am looking for) than its x86 counter part, namely, Vista 32 bit. I was able to find the registry entry I needed in Vista x86 and XP but in Vista x64, there seems to be a TON of programs that are missing (located in HKEY_LOCAL_MACHINE\SOFTWARE). I have all my programs installed into the default directory (C:\) which is the primary partition.

Vista x64 installs into the normal "C:\Program Files" directory if it detects that the installer supports 64 bit support, otherwise, it will install into the "C:\Program Files (x86)" directory for all 32 bit applications. I want to know if the registry has a different location for these two types of architecture, because I can't find where the registry entrys would normally be located in Vista x64.

The x86 programs are in the registry.

Look at these screen shots...


On the right, is regedit.exe opened to HKEY_LOCAL_MACHINE\SOFTWARE. On the left is my default folder for normal 32 bit applications to be installed, (C:\Program Files (x86))*. Notice how barely any of the installed programs are showing up in the registry.

*not all programs are displayed.


This is where my default x64 bit applications are installed (C:\Program Files). Notice too that not all programs are being displayed in the registry.

On any other x86 machine, I can look at the registry and see all programs installed no problem, but I don't know much about how x64 machines deal with the registry. Please help...

All I can think of is to try searching for the program's name in the Registry (Regedit > Edit > Find).

After doing a bit more research, I found the answer.

The default path for x86 program installations in Vista x64 are:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\

BTW, thanks for help managed.

The programs are also under HKEY_CURRENT_USER\Software - Sorry for the late reply, only just scanned the new posts!
