Setting Notepad++ as default text editor requires changing a reg key

I'm trying to set the permissions of a registry key from the command line. Easy to do in regedit, but this is all part of a system customization script.

The command line is;

regini -h HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\fileexts\.txt\userchoice [1 5 7] test.txt

But it fails with;

REGINI: Failed to load from file '5' (3)

[1 5 7] are the permissions I'm trying to set, and test.txt contains;

ProgID = REG_SZ Applications\notepad++.exe

(Key name, type and the value I'm trying to set)

Windows 10 1809; Regini /? for help.

What am I doing wrong?

You can use Reg.exe command-line for example below command makes Notepad++ default batch script (.bat) editor.

Code:

Reg.exe add "HKCR\batfile\shell\edit\command" /ve /t REG_EXPAND_SZ /d "\"C:\Program Files\Notepad++\notepad++.exe\" \"%%1\"" /f

Thanks for that.

I already have something similar already configured.

I had set it to be the default replacing notepad. To accomplish that the registry tweak I mentioned is required. I can easily do this after a system is installed with regedit, but I'm trying to make the whole process as automatic as possible.

Hi @Compumind. Thanks for the link.
I had already seen that.

What I'm looking for is assistance with the regini command.

Specifically why does this command fail.
regini -h HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\fileexts\.txt\userchoice [1 5 7] test.txt

I need to change the title of this post. It should read "How to change registry permissions from the command line"

I use a few other text editors. To make Notepad++ run in place of notepad use IFEO.

Code:

reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\notepad.exe" /v "Debugger" /t REG_SZ /d "\"%ProgramFiles%\Notepad++\notepad++.exe\" -notepadStyleCmdline -z" /f

Yes, I've seen that too on ghacks and winaero.

What I'm after is finding out why the regini command fails. I want to change permissions of a registry key from the command line so I can add it to a setupcomplete.cmd script.

Notepad++ was just one example of where this is needed, but is not the only reason for changing permissions on registry keys. There are others.

I think you may be having issues because of the key you're trying to edit.

HKCU\...\FileExts seems to have some magical extra protction from modificat by applicatons/scripting.

I'm not familiar with regini, but I would suggest testing on a dummy key of your own creation (outside of FileExts & its subkeys). If a similar command successfully modifies those permissions, your problem is not with regini or your syntax, but the key itself.
