I have used the following command line for many years:
"C:\Program Files\CCleaner\CCleaner.exe" "/AUTO"
As of CCLeaner 5.44 and continuing with 5.45, this no longer works. CCLeaner starts in the background, and almost instantly quits without accomplishing anything.
If I stay with CCLeaner 5.43, all works as expected.
If I run the GUI for CCLeaner 5.44 or 5.45, the program works as expected.
Just can't execute the clean from the command line anymore.
