Thanks, that has sorted it out. Now it runs.
Maybe Piriform could make the app only use system fonts so when it is used on a Mac in a commercial print environment (pretty common) where fonts get enabled and disabled every day, this doesn't happen.
That seems like a good idea.
The app crashes on launch, Mac Pro 1,1 running OSX 10.6.8, 13GB ram. This happens every time I try to launch the app.CCleaner crash log.txt
I've attached the crash log too.
