Inno Setup - 文件正在使用，禁止跳过/取消

Question

I have configured "Inno Setup" as needed, but there is one point which I'm not able to modify.

We have an application which is installed on a network folder on the customers server. Basically updating the files works as expected.

If some client on the network, someone which has not initiated the update, has opened the application I'm receiving an messagebox/errorbox "delete file failed.... file is in use by another process" - including 3 buttons "try again", "skip this files (not recommended)", "cancel installation". I have attached an example picture (found on the internet, but the same message).

There you can see the 3 buttons. I want to disable "skip this file" and "cancel installation". The user should have the ability to hit "try again" - they should get stucked until all client have closed their application.

I do not think you can alter that message box.

There are two alternatives:

• You can delete the target file using your own code before installing the new version, not allowing to proceed until the file is gone.

   [Files] Source: "Source: "C:\\SampleApplicationData\\*"; DestDir: "{app}\\SampleApp"; \\ Flags: recursesubdirs createallsubdirs; BeforeInstall: ForcedDelete [Code] procedure ForcedDelete; var FileName: string; Deleted: Boolean; begin FileName := ExpandConstant(CurrentFileName); repeat if not FileExists(FileName) then begin Log(Format('File %s does not exist', [FileName])); Deleted := True; end else if DeleteFile(FileName) then begin Log(Format('File %s was deleted', [FileName])); Deleted := True; end else begin MsgBox(Format('Error deleting %s.', [FileName]), mbError, MB_OK); Deleted := False; end; until Deleted; end;

  Though I still believe the code should at least allow an abort.

• Or use restartreplace flag .
