Inno Setup - bcdedit is not working

Question

I need to submit the command:

bcdedit /set {default} recoveryenabled No

but it's not working with Inno Setup.

I have tried as below:

[Setup]
PrivilegesRequired=admin

[Run]
Filename: "{cmd}"; Parameters: "/c ""bcdedit.exe /set recoveryenabled No""";

But I still see the No is not applied. As you can see below, it still remains Yes. But when I manually do the same command from command prompt, it works. Any idea why it is not working within Inno Setup? I'm also running the setup.exe as administrator.

C:\windows\system32>bcdedit /v

There can be many reasons. It's difficult to tell as you didn't provide much information to debug this.

Using /K instead of /C is the first step, as it will keep the cmd.exe window open, so that you can see, if there are any error messages.

When I use your [Run] section entry in a trivial installer, I get:

'bcdedit.exe' is not recognized as an internal or external command, operable program or batch file.

On my system (and I believe it would be the same on yours), it's because I'm running Windows 64-bit and the bcdedit.exe is in C:\Windows\System32. As Inno Setup in a 32-bit application, it by default gets redirected to C:\Windows\SysWOW64 (32-bit version of C:\Windows\System32). And there's no 32-bit version of bcdedit.exe.

Add Flags: 64bit to make Inno Setup find 64-bit version of bcdedit.exe.

Also, there's no point running .exe application via command interpreter (cmd.exe).

[Run]
Filename: "bcdedit.exe"; Parameters: "/set recoveryenabled No"; Flags: 64bit

Or use 64-bit install mode.
