Fail to delete some registry keys

pierrep

Hi, I have run Driver Cleaner.net yesterday for the first time, having a "Access denied" message when trying to re-install a ATI Radeaon X600 driver in Lenovo Z60m with XP Pro. Problems begun after I made a bios upgrade.... New bios was installed OK, I had a driver update after that and the update failed. Now I only have the "VGA save" default driver. I run Driver Cleaner following the instructions (safe mode..) but some keys cannot be deleted from regystry: it says:
Exception: ThrowSecurityException
Error: Requested registry access is not allowed.
The keys are:
HKEY_LOCAL_MACHINE\SOFTWARE\ATI Technologies Inc.
Extra: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Eventlog\System\Ati HotKey Poller
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Eventlog\System\ati2mtag
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\R oot\LEGACY_ATI_HOTKEY_POLLER
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\E ventlog\System\Ati HotKey Poller
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\E ventlog\System\ati2mtag
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\Root\ LEGACY_ATI_HOTKEY_POLLER
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\E ventlog\System\Ati HotKey Poller
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\E ventlog\System\ati2mtag
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Enum\Root\ LEGACY_ATI_HOTKEY_POLLER

I try to install the Driver anyway... but I still the "Access denied" error. What can I do ?
Thanks for the help

Hi,

those keys are normal that they can't be deleted. That is not a problem. Can you give me the full error you get when you install a new driver?
