Get acess to Registry Editor in C#

Question

Hello!
Hi! I'm developing an application that lists windows programs in C#.NET. It searches through the Registry Editor, accessing three different locations, namely:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall HKEY_CURRENT_USER\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall

when I'm trying to access the first path, the program is always directed to the second path and I have no idea why this is happening. can anybody help me?

When I use

key = Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall ");

the program goes to path : "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall"

Answer 1

there are two registries, 32 bit & 64 bit.

you appear to be accessing the 32 bit version on a 64bit o/s, thus the "\WOW6432Node\". the 32 bit registry values are loaded into the 64 bit registry under this node.

explicit access:

RegistryKey localKey32 = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, RegistryView.Registry32);
RegistryKey localKey64 = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, RegistryView.Registry64);
