The statement of Jason is right, the operating system is the problem, the below code will help you to resolve. RegistryKey localKey; if(Environment.Is64BitOperatingSystem) localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64); else localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32); string value = localKey.OpenSubKey(“RSA”).GetValue(“WebExControlManagerPth”).ToString();
You can use RegistryKey.OpenBaseKey to solve this problem: var baseReg = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64); var reg = baseReg.CreateSubKey(“Software\\Test”);
Here’s a full, complete example with a bit more detail and cleaner code than in the linked question and should provide a better answer. Quite timely as I’ve recently finished porting the code posted previously, to use proper ProgId elements so this is fresh in my mind 😉 In regards to the ‘what here’, you … Read more
I discovered that I could solve my problem using the flag: KEY_WOW64_64KEY , as in: result = RegOpenKeyEx(key, s, 0, KEY_READ|KEY_WOW64_64KEY, &key); For a full explanation: 32-bit and 64-bit Application Data in the Registry
For Windows 7 & 8 & 10 Add custom item to Context Menu: Sublime Text 3 Path to the application: C:\Program Files\Sublime Text 3\sublime_text.exe.

For allowable key and value names, see the MSDN page on Structure of the Registry. In particular: Each key has a name consisting of one or more printable characters. Key names are not case sensitive. Key names cannot include the backslash character (\), but any other printable character can be used. Value names and data … Read more
I have figured out why this is happening. With the WiX installer being compiled on a x86 platform, Windows 7 picked it up as the 32-bit installer with 32-bit registry keys. Windows 7 64-bit handles 32-bit registry entries by doing just what I saw happening. The program was still registered; it was just not in the … Read more
It can happen if you are on a 64-bit machine. Create a helper class first (requires .NET 4.0 or later): public class RegistryHelpers { public static RegistryKey GetRegistryKey() { return GetRegistryKey(null); } public static RegistryKey GetRegistryKey(string keyPath) { RegistryKey localMachineRegistry = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, Environment.Is64BitOperatingSystem ? RegistryView.Registry64 : RegistryView.Registry32); return string.IsNullOrEmpty(keyPath) ? localMachineRegistry : localMachineRegistry.OpenSubKey(keyPath); } public … Read more
Send the file as a parameter to regedit.exe: Process regeditProcess = Process.Start(“regedit.exe”, “/s key.reg”); regeditProcess.WaitForExit();
