[Files] Combining flags external and download with parameter Tasks

[Michal TURZO]

I have problem when i combine flags external and download with parameter Tasks.

- The file is not downloaded on setup initialisation

- When it should be extracted, I get error:

Internal error: Unexpected Download flag.

how to reproduce:

Add Tasks parameter to last [File] in Examples/DownloadFiles.iss:

; This archive will be downloaded and extracted without verification
Source: "https://github.com/jrsoftware/issrc/archive/refs/heads/main.zip"; DestName: "issrc-main.zip"; DestDir: "{app}"; \
  ExternalSize: 15_000_000; Flags: external download extractarchive recursesubdirs ignoreversion

->

; This archive will be downloaded and extracted without verification
Source: "https://github.com/jrsoftware/issrc/archive/refs/heads/main.zip"; DestName: "issrc-main.zip"; DestDir: "{app}"; \
  ExternalSize: 15_000_000; Flags: external download extractarchive recursesubdirs ignoreversion; Tasks: SomeTask

Am I doing something wrong, or it is a bug?

Looks like a bug, will check it out, thanks for reporting.

I suppose that when it checks if there are archives to download, it misses this one because of failing to recognize the task is selected.

Greetings,

I found a workaround. 

Instead of Task, I used Check parameter. And check for task from provided function. Something like:

[Files]

Source: ...; Check:CheckSomeTask

[Code]

function CheckSomeTask(): Boolean;
begin
  Result:=WizardIsTaskSelected('SomeTask');
end;

Ok, great 👍 In the meantime, I also found and fixed the issue (it was basically a typo), so it should work with Tasks as well in the next version, which was already scheduled for release tomorrow.
