#1871 closed Bug (No Bug)

RegRead error on Win64 using Win32 compile

Reported by: solid_light@… Owned by:
Milestone: Component: AutoIt
Version: Severity: None
Keywords: RegRead Win64 Cc:


On a Win64 system (mine was Windows 7), run the following code:

#Region ; Directives created by AutoIt3Wrapper_GUI
#EndRegion ; Directives created by AutoIt3Wrapper_GUI
Local $7Zip = RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\7-Zip", "Path") & "7z.exe"

It will FAIL even if 7-Zip is installed. The only solution is to comment out or remove the first 3 lines. I discovered this after compiling my code into a Win32 command and the compiler added the directives. I suspect the problem lies with the #AutoIt3Wrapper_UseX64=n wrapper, and I don't believe it's been fixed in the v3.3.6.1 release. I'll provide any additional information that's requested. Attached is a sample .au3 illustrating the above problem.

You are aware that in 32bit mode the following path "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\" is used for key "HKEY_LOCAL_MACHINE\SOFTWARE\"?

So does any 7-zip key exists there?

this looks like just another case of "someone jumping into the x64 world without reading any freaking documentation".

No bug.

Use the forum for help.

@ Jos & Admiral,
Thanks for your input. I seriously thought it was a bug - even after I had read through the help files (it's a little unclear to the uninformed). I was unaware of how 64-bit Windows accessed the registry. Much appreciated!
