How do i standardize the path of Adobe to open a PDF file?

Question

Hi all,
In one of my forms, i have created a Text Item (named as PDF1 ) in which i will display the name of PDF file and also have created a check box (named as CH1 & put in the block 'PDFCHK' ).
Here what i am doing is when i click on the check box, the PDF file opens (name present in the Text Item).
So i have written the following code.
DECLARE
  filename VARCHAR2(256);
  APPID PLS_INTEGER;
BEGIN
  IF :pdfchk.CH1 = 1 THEN
  filename :='C:\'||:PDF1||'.pdf';
  AppID := DDE.App_Begin('C:\Program Files\Adobe\Reader 11.0\Reader\AcroRd32.exe '||filename,DDE.APP_MODE_MAXIMIZED);
END IF;
END;
The problem here is that since i have hardcoded the path of Adobe (C:\Program Files\Adobe\Reader 11.0\Reader\AcroRd32.exe) , there is a problem.
In all the systems different versions of Adobe is installed & in different folder. So it does not work on all systems. So how do i standardize the code such that it searches the path itself or what can be the remedy to this???
Please help me on this?

Turn off the "Verify ...on Open" preference in the "Signature Verification Preferences" dialog. How to get there depends on the Acrobat/Reader version you have. in XI it comes up when you go to Edit->Preferences->Signatures->Verification->More...
