Detect Missing File or RegEntry

Hmm I have one Problem..

Adobe Reader for example (and many other programs) on a update to the next version forgets to clean some files...

So I have to check for a file which is missing and some data which is still left.

I want to do following:

DetectFile=%ProgramFiles%\Adobe\Reader 8.0\Reader\

AND (optional)

DetectNoFile=%ProgramFiles%\Adobe\Reader 9.0\Reader\AcroRd32.exe

(Alternative Implementation) DetectFile=%ProgramFiles%\Adobe\Reader 9.0\Reader\AcroRd32.exe|MISSING)

(Alternative Implementation) MissingFile=%ProgramFiles%\Adobe\Reader 9.0\Reader\AcroRd32.exe)

FileKey1=%ProgramFiles%\Adobe\Reader 8.0\Reader\|*.*|REMOVESELF

Could you consider this for further development

Thanks Sascha
