Some registry entries are identified as having missing or invalid targets when an executable is present but the registry key suffixes the full path (or uses symbolic names) to the executable by appending for example ",1" to indicate that it is an icon within the executable that is the target. The Windows Journal "%ProgramFiles%\Windows Journal\Journal.exe,1" is an example. Other registry keys point to commands which have arguments appended to them, for example uninstallers. Registry cleanup needs to be aware of this and not flag these as errors unless the actual target executable or path does not exist or is invalid.
