windows - Change registry value permission command line or NSIS -

i'm trying grant ordinary users write access registry value created.

they cannot have write access parent key.

through regedit, it's simple: 1. select value 2. edit permissions (change accordingly) 3. ok

however i'm struggling same via command line or nsis.

• the command regini has nice method changing key permissions. if worked changing value permissions, script installer.
• the nsis plugin accesscontrol has nice method changing key permissions no evidence of changing value permissions.

in case, key hklm\software\microsoft\windows\currentversion\run not modify permissions of.

how can change only permissions of value i've created? how can regedit allows, silently through command line or nsis?

the value like:

[hklm\software\microsoft\windows\currentversion\run] "my value"="c:\please\let\me\change\permissions\sadface.exe" 

note, scripted software installer build script run on mac, linux , windows (nsis allows this). recommendations bundling special dlls or windows executable ok long they're bundled , chained against @ install time. solutions including tools such windows sdks cannot accepted unless footprint small , long dlls can bundled , included lgpl 2.1 project. e.g. installing users have run this, solutions need reasonably portable/distributable.

as @noodles mentions in comment above, it's not possible change value permissions, no solution exists. registry editor providing key permissions, observable looking @ window title, , undesired particular solution.
