Checking existence of a file in Inno Setup Internal Temporary folder

Question

I want my Inno Setup Script to search for my setup's .TMP file which usually creates in currently logged user's Local Application Data folder and give user a message box saying "Your Setup's Temporary Source seems to be created successfully."

I wrote a code to do so:

 if CurPageID = wpLicence then begin
   if FileExists((ExpandConstant('{localappdata}\Temp\is-*****.tmp\MySetup.tmp'))) then begin
     MsgBox('Your Setup''s Temporary Source seems to be created successfully.', mbInformation, MB_OK);
     MsgBox('It is located in: <<I WANT TO GET THE FOUND FILE''S FULL PATH HERE>>', mbWarning, MB_OK);
   end;
 end; 

But, even my setup's temporary file (MySetup.tmp) exists when the setup starts, I'm not getting those message boxes.

What is the problem in this code?

Is the is-***** ignored when searching?

UPDATED QUESTION

I mean The Temporary Directory shown in below image. It contains the internal Temporary File of the Setup Wizard. This is usually named like {#SetupName}.tmp...... Not the other Temporary Directory which Inno Setup extracts Files of the Setup. such as ISSKin.dll or any externally used files.

Any help would be greatly appreciated.

Answer 1

The FileExists function does not support wildcards, not even in a file name, let alone in a name of a parent folder.

See How to test using wildcards whether a file exists in Inno Setup.

Though in your case, just use the ParamStr(0).

FileExists(ParamStr(0))
