I do not have these programs installed so I am unable to test this but I think you can leverage some of the built in Windows commands. The example I included below uses the FORFILES command. Hope this helps or at least leads you in the right direction, else we can work it out.
FORFILES /p "YOURPATHHERE" /m *.* /c "cmd /c if C:\Program Files (x86)\PDFCreator>PDFCreator.exe /NOSTART /PF @file"
