Wiper Problem (WIN7)

...first...sorry for my bad english. I have problems with wiper.

On Sunday I have my PC (Win7) sold and would like to use CCleaner wiper (entire drive). But the hook for it can not be activated and I do not understand why ... thanks for the help.

i don't quite understand your problem but i guess, you cannot select drive C:\ or windows partition, is it?

to wipe the disk completely,you need to attach the hard disk to another computer

or you can use windows installation disk to wipe the partition completely

If you're wanting to keep the OS installed you can try using Wipe Free Space instead, and make sure to tick the MFT option box.
