DeleteAfterInstall flag not deleting files once installation is complete

Question

I've got some additional files to install some runtime engines that are required for my application (Access database engine and Crystal Reports runtimes).

I'm setting them to use the deleteafterinstall flag, so once they've been installed and the application install is complete, it should delete the files, however, I've tested it on my work PC and my personal laptop and despite the application and runtimes being installed without any issues, the runtimes installers aren't being deleted.

[Files]
Source: "\\my_Directory\AccessDatabaseEngine.exe"; DestDir: "{app}"; AfterInstall: RunAccessInstaller; Flags: deleteafterinstall;

[Code]
procedure RunAccessInstaller;
var
   ResultCode: Integer;
begin
   if not Exec(ExpandConstant('{app}\AccessDatabaseEngine.exe'), '', '', SW_SHOWNORMAL,
               ewWaitUntilTerminated, ResultCode)
then
   MsgBox('Microsoft Office Engine installer failed to run!' + #13#10 +
          SysErrorMessage(ResultCode), mbError, MB_OK);
end;

After removing AfterInstall: RunAccessInstaller along with the RunAccessInstaller procedure itself, this still doesn't delete the file.

The script now appears as below, so it seems as though the deleteafterinstall flag isn't working.

[Files]
Source: "\\server\common\David\Iconysis Agent Installer Files\AccessDatabaseEngine.exe"; _
         DestDir: "{app}"; Flags: deleteafterinstall;

The full log file when running a fresh install onto my Desktop (installation run without installing AccessDatabaseEngine.exe)

There are two references to AccessDatabaseEngine.exe in the log file.

That most probably means that you have two entries for AccessDatabaseEngine.exe in the [Files] section.

I guess that you have one explicit entry for AccessDatabaseEngine.exe and another wildcard entry what happens to match the same file. Something like:

[Files]
Source: "\\my_Directory\*"; DestDir: "{app}"
Source: "\\my_Directory\AccessDatabaseEngine.exe"; DestDir: "{app}"; \
    Flags: deleteafterinstall;

The first entry installs AccessDatabaseEngine.exe. And it does not have the deleteafterinstall flag. The second entry does not install the file (as it's installed already), hence its deleteafterinstall has no effect.
