Eraser and Windows7

Hello all,
thanx a lot for this friendly user program.I have a problem maybe this is a little problem but i couldnt solve...

İm using Windows7 and i cant erase C and D drivers unused space i gave an error message like this;

''Files in D:\System Volume Information did not have its cluster tips erased because of the following error: Access to the path 'D:\System Volume Information' is denied.''

I gave that error message after that erasing process stoped when 30 percent.Im waiting for your advices...
Please read the FAQ, notably the post on Getting to know Eraser 6, and follow the guidance on running Eraser as Administrator.

The likelihood is that you need to run Eraser as Administrator. Did you do so?

System Volume Information is a system-protected folder, it's only natural that Eraser cannot erase it. Don't worry too much about it, Eraser's error reporting is quite verbose in this release.
