re: Data is invalid - can't install device Thursday, November 5, 2009 at 9:27 am Windows XP Annoyances Discussion Forum Posted by Chris Raisin (1 messages posted) The ultimate solution to this to this problem is supplied by Microsoft themselves! Simply download the utility PNPReg.exe from their site http://support.microsoft.com/default.aspx?scid=kb;en-us;810509 and run it from the "command" prompt with the switch "-l" ("l" for Lock). This locks the ENUM branch of the registry to prevent unauthorised changes. The main culprit is Leadtek WinFast Titanium 200 driver installation software. Without the lock in place, the driver installation process changes the data in the ENUM values in the registry (something it should not do) thus causing the error. After running the lock, simply go into Conrol Panel and in Device Manager find devices which show errors. From there right click on the device and select "Update Driver".....Voila! All fixed without having to change any permissions in the registry........Took ages to find this fix, but it was worth it! :-) Written in response to: re: Data is invalid - can't install PCI device (James Anoviejo: Monday, November 10, 2008 at 6:03 am) There are presently no replies to this message.
