Inno Setup: How to manipulate progress bar on Registering section?

Question

Just like my question in Inno Setup: How to manipulate progress bar on Run section?, which Martin Prikryl gave me an excellent suggestion, I want to do the same (change the style of the progress gauge) in the registering section, I mean, just before the Run section, when Inno Setup registers the DLLs / OCXs (regserver flag in [Files]).

I tried using some of the PageID to make it work, which I think is the wpInstalling one, comparing it to when it values goes to 100, it changes to Marquee style, but I didn't make it work.

Thanks a lot.

There's no event that is triggered before the registration.

The closest you can get is using AfterInstall parameter of the last installed file (not the .dll):

[Files]
Source: "mydll.dll"; DestDir: "{app}"; Flags: regserver
Source: "myfile1"; DestDir: "{app}"
Source: "myfile2"; DestDir: "{app}"
...
Source: "myfileN"; DestDir: "{app}"; AfterInstall: AfterLastFileInstall

[Code]

procedure AfterLastFileInstall;
begin
  Log('Last file installed, file registration is starting');
  WizardForm.ProgressGauge.Style := npbstMarquee;
end;

Another option is to handle CurInstallProgressChanged event and wait for CurProgress = MaxProgress:

[Code] 

procedure CurInstallProgressChanged(CurProgress, MaxProgress: Integer);
begin
  if CurProgress >= MaxProgress then
  begin
    Log('Everything is installed, file registration is starting');
    WizardForm.ProgressGauge.Style := npbstMarquee;
  end;
end;
