Create Registry keys under HKEY_LOCAL_MACHINE in vista/win7.

Hi,
I have a piece of VB6 code that writes string data under HKEY_LOCAL_MACHINE using RegCreateKeyEx API. this works well under XP but under vista/win7 it does not write. I tried "run as administrator" but even then it does not work. With UAC off it works, except in 2 of the 7 PCs that I tried in. I also tried the following code I found on microsoft site

const HKEY_LOCAL_MACHINE = &H80000002
strComputer = "."
Set objReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\default:StdRegProv")
strKeyPath = "SOFTWARE\NewKey"
objReg.CreateKey HKEY_LOCAL_MACHINE,strKeyPath

but this also does not work.

What would be a foolproof method of writing the data.

Thanks & regards,

DJ

This still sounds like it's a UAC issue...
The HKLM\Software key in WinV/Win7 requires administrator rights. Are you sure that running the application with "Run As Administrator" doesn't work?

Hi graye,
I just checked again. the 2 machines where I have problem even when I use "Run as Administrator" are running 64 BIT versions of Win 7. I think this has something to do with 64BIT rather than UAC. What I dont understand is that RegCreateKeyEx exits without any error code. It makes it look as if the key has been created.

Thanks & regards,

DJ
