Inno Setup remove specific reg key after uninstall

I try to remove a registry key after uninstalling it in Windows, but I couldn't get it working somehow. I tried everything which was listed here: Inno Setup: Removing a problematic registry key left by another program

I checked different docs of Inno Setup:

I ended up with this:

; Basic setup for a JavaFX application

#define AppName "Practicumopdracht OOP2"
#define AppVersion "1.0.0"
#define AppPublisher "Remzi Cavdar"
#define AppURL "https://twitter.com/remzicavdar"
#define AppExeName "practicumopdracht.jar"
#define AppExeDir "C:\Users\Remzi\Projects\student-1\out\artifacts\practicumopdracht_jar"
#define AppIcon "app.ico"
#define ProjectDir "C:\Users\Remzi\Projects\JavaFX-Setup"

    MsgBox('Java JRE installer failed to run!' + #13#10 + ' ' + SysErrorMessage(ErrorCode), mbError, MB_OK);

This is what I'm trying to remove after uninstall:

Solution

I found a solution to my registry question. I needed to check for both 32-bit and 64-bit.

[Registry]
Root: HKCU; Subkey: "Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Store"; ValueType: binary; ValueName: "{app}\unins000.exe"; Flags: dontcreatekey uninsdeletevalue
Root: HKCU64; Subkey: "Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Store"; ValueType: binary; ValueName: "{app}\unins000.exe"; Flags: dontcreatekey uninsdeletevalue; Check: IsWin64

I found the answer here: Writing 32/64-bit specific registry key in Inno Setup and https://jrsoftware.org/ishelp/index.php?topic=registrysection also mention this with HKLM64 example, but I read things to fast to notice it.
