Yes - I have tried three different command lines
"C:\Program Files\CCleaner\CCleaner64.exe" /AUTO
%ProgramFiles%\CCleaner\CCleaner64.exe /AUTO
C:\"Program Files"\CCleaner\CCleaner64.exe /AUTO
The one I submitted I found on the forum - I didn't think it would work but I gave it a try and forgot to change it back.
Oddly enough, this command line is the only one that generates a *.dmp file.
"C:\Program Files\CCleaner\CCleaner64.exe" /AUTO
The program works just fine when I run it normally - just can't invoke it with a batch file.
