regread cant read x64 keys remote

[anonymous]

If you run regread from a x86 os PC and want to read a regkey from a x64 os remote than this is not working.

Example:

RegRead("\\REMOTEx64SYSTEM\HKLM64\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install", "LastSuccessTime")

This key doesn't exists in the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node so the command fails with @error 1 = unable to open requested key

It makes no difference if run with HKLM or HKLM64 but in my opinion HKLM64 should do the job

Are you running this with the X64 version of AutoIt3?

I suspect NO as it is running from a PC 32-Bit ...

I am running this from a Win7 x86 pc with Autoit x86

Here is some more info on this.

Does the internal AutoIt registry functions use the KEY_WOW64_64KEY flag when HKLM64 is specified?

[Jpm]

Yes it does.
But I am not for sure a PC running a 32-Bit version can reference the 64-bit specific registry info

There must be a way, cause also reg.exe can read x64 regkeys from a x86 system:

Not working:

reg query "\\REMOTEx64SYSTEM\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install" /v LastSuccessTime

Working:

reg query "\\REMOTEx64SYSTEM\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install" /v LastSuccessTime /reg:64
