Some Clean Options Are "Grayed Out"

Howdy folks. I just installed CCleaner 2.20.920 and have been looking through some of the Cleaning options. Under "Windows" all of the Advanced options are grayed out and the last three of the System options are also grayed out so I can't use them. Does anyone know if there's a simple reason for this?

I have Vista Home Basic SP1.

Thanks!

Do you mean if you put a tick in one of the greyed out options it doesn't become ''live''?

Also best not to tick anything in advanced til you understand the program and what it cleans there.

It's like they're dead. I can't check them or uncheck them. You can see them, but they're dead.

May be an idea to download a new installer, and then run it to install over the top of the one you have.

Sounds like all did not go well with your install perhaps.

Just downloaded the new version 2.21 and it's working. Those options are still unchecked by default but now when I check them they work. Excellent!

Glad it's all working for you now norel :)
