Hello there - I have this issue too with "This device is not present, not working properly or all the drivers are not installed. (code 24)". I have Win7 64 and I am a UK customer taking the McAfee suite via BT's Netprotect Plus.
I opened regedit and looked for this entry.
I dont have a entry line for "Load Arg" .
The path is per the examples above and looks correct .
When I try to modify the "Start" value to 3, regedit tells me I cant change it "error editing value".
What should I do?
Sometimes when editing the Registry Keys, one needs to take ownership of the keys being edited or deleted, before the change is allowed.
You need to right-click on the Key and click Permissions. Also before starting, make sure that you are in your Admin User ID.
You need to turn OFF Access Protection before making changes in the registry. To do this Open McAfee User Interface > Navigation > General Settings and Alerts > Access Protection > Uncheck > Click Apply.
Retry changing the value in the Registry and Re -enable Access Protection even if you are not able to suceed.
