Have you tried:

System.Diagnostics.Process.Start("regedit.exe");

I have tested this code in x64 machine with LinqPad and works.

Here is orginal topic

@jeongseok-park I think this is connected with priviliges problem. But I only guess. What type of application you got? web or win forms? – r.piesnikowski Aug 14 '13 at 07:04
My allpication type is Winforms. and I want to see result of 'Process.Start("regedit.exe")' same as 'Window Key +R' but it's different. Execute regedit.exe through 'cmd.exe' also different with 'Window Key + R' result – JeongSeok Park Aug 14 '13 at 07:21
cmd.exe result is same as 'process.start' result – JeongSeok Park Aug 14 '13 at 07:28
@jeongseok-park Please do this: Open Event viewer in Control Panel -> System and Maintenance -> Administrative Tools -> Event Viewer -> Windows Logs -> Applications. After do action check for errors and put stacktrace. – r.piesnikowski Aug 14 '13 at 08:40

I've just had the same issue: Check your C# app isn't built for x86.

If a 32bit process executes regedit, then windows will launch the 32bit version of regedit. In this version HKLM\Software actually points to HKLM\Software\Wow6432Node.

If you use start -> run -> regedit (Assuming your running a 64bit version of windows), this will launch the 64bit version of regedit. Now you can see the HKLM (or HKCU) Wow6432Node key exists.

Why I can't see 'wow6432node' when using process.start("regedit.exe")?
