Migrating setup script from 6.5.1 to 6.5.2 errors

[JustDj]

Hi everyone,

In Inno Setup version 6.5.1, this code works:

<event('CurInstallProgressChanged')>
Procedure SetInstallStatus(CurProgress, MaxProgress: Integer);
begin
InstallStatusLabel.Caption := WizardForm.StatusLabel.Caption; InstallFilenameLabel.Caption := WizardForm.FilenameLabel.Caption;
end;

But starting from 6.5.2 and newer, it throws this error:

TScriptRunner.SetPSExecParameters: invalid type

I’ve gone through all the documentation and even asked every AI I could find until I hit their limits — and only now I’m coming here.

Could anyone point me in the right direction? I know that everything works fine on a clean Inno installation, but I’d like to understand what exactly changed in the newer versions that broke my setup.

Hi,

This is a bug caused by recent cleanup. I have fixed it now and will post a new build later this week.

Thank you for reporting it.

Greetings,
Martijn
