Problem with HP System Recovery

Hi,

I've a question for you.

I'm trying to install HP System Recovery for Windows 7 Ultimate (x64), but it doesn't want to work.

I've downloaded it here: http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?cc=it&lc=it&dlc=it&softwareitem=ob-75985-1 but it doesn't work.

The installer says this: http://prntscr.com/1hp1rc and if I go to: C:\SWSetup\sp45602 I find a folder.

If I open that folder, I find these files: http://prntscr.com/1hp209

If I click on "RecoveryMgr_x64", it says that HardDisk.dll was not found, and I need to install it again for solve this problem.

I've installed it 2/3 times, and I have always got that error.

How can I install it?

Thank you for your reply.
