Writing to registry in x64 Win7

Recommended Posts

I checked the bug reports and also the documentation and didn't see anything specific to the issue I've found. For example, the help file says:

When running on 64-bit Windows if you want to write a key or value specific to the 64-bit environment you have to suffix the HK... with 64 i.e. HKLM64.

Which doesn't necessarily tell me anything regarding what I am seeing. Here is an example:

RegWrite ( "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SoftGrid\4.5\Client\AppFS\ServiceInclusions" , "Service1" , "REG_SZ" , "NAV" )

Will write to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\SoftGrid\4.5\Client\AppFS\ServiceInclusions (GOOD!)

RegWrite ( "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\SoftGrid\4.5\Client\AppFS\ServiceInclusions" , "Service1" , "REG_SZ" , "NAV" )

Will write to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Wow6432Node\Microsoft\SoftGrid\4.5\Client\AppFS\ServiceInclusions (BAD!)

Is this behaviour what the help file is trying to say with what I quoted?

No, what the help file told you that you need to do is instead of using HKLM you'd used HKLM64. Or, in other words, instead of you using HKEY_LOCAL_MACHINE, you would use HKEY_LOCAL_MACHINE64 (or maybe _64, I'm not sure as I don't have an x64 machine to check). HKLM is the shorthand way or writing HKEY_LOCAL_MACHINE.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

How to ask questions the smart way!

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

The code is in a compiled 32bit EXE.

EDIT: I am fine with using the first option I marked as GOOD!. This puts the key where I need it. However I wanted to point it out in case it is a bug, or if further info needs to be put in the help file regarding the RegWrite behaviour in x64.

RegWrite ( "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\SoftGrid\4.5\Client\AppFS\ServiceInclusions" , "Service1" , "REG_SZ" , "NAV" )

Will write to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Wow6432Node\Microsoft\SoftGrid\4.5\Client\AppFS\ServiceInclusions (BAD!)

But it just did what you told it to.

And while we're talking about x64 Windows and registry, some good reading is:

Registry Redirector, and the various links on that page.

And for easy access to HKLM32 and siblings in AutoIt, see

Edit: and if you're really serious, Programming Guide for 64-bit Windows. You'll find the registry article and many other interesting things inside.
