How to delete a installed application using AppId in inno setup?

Currently i have used the following code to delete the old version
directory of my application, below code works fine by finding the
application with the app name. I want to find the application using it
UNIQUE APPID, Can someone please help me out regarding this issue.
procedure DeleteExistingVersion(); begin
MsgBox('Deletion Starts',mbInformation, MB_OK);
if (DirExists (ExpandConstant('{pf}\APPLICATION NAME'))) then
begin
