Reduce File Size functionality

Question

Hi,
            I want to automate the Reduce File Size functionality available in acrobat in one of my plug-in application. This is because,
                      Earlier I used "PDDocSaveWithParams" to set the PDF file version as per user selection, but it was failing many times to set PDF Version to lower versions.  So later I did the following change.
            I used "AVDocSaveOptimized" to set the PDF to the user selected version(It may be to a lower or to a higher version).  It was working fine.  but later when it is used on acrobat Standard version. It is failing to do the same, as "PDF Optimizer" is abesent in Standard.
            I need to find an alternative to set the compatible PDF version, which works on both Standard and professional.   So if I am able to automate the Reduce File Size funciton from acrobat window, it will set the PDF version of the file to the user selection.  Can anybody tell me, how can i use it?  if it is through AVCommand, then which is that command.  
        If not, what alternative i can use to set the PDF version of the file to the user selection?
         Please help me,
your help would be highly appreciated.

But the in that funciton
it is working fine on Acrobat Professional, but the same without any changes (and for the same set of PDF files),
it is crashing on Acrobat Standard.    I don't know what's going wrong here.  I have just added code part below,  Can you tell me, where it is creating problem and what's remedy for this?
    if(iAVersion == 0) iAVersion = kPDFOptRetainVersion;
    else if(iAVersion == 4) iAVersion = kPDFOptAcrobat5;
