Invaild Data Fix for WinXP

This error appears to be due to a protection problem in the Windows registry and can occur with a variety of drivers (sound cards and SCSI drivers have been reported). To fix this problem, go to Start, Run... and type "regedit" without the quotes to run the Registry Editor. Navigate to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ENUM\PCI

and you will see a number of keys of the form "VEN_xxxx", where xxxx are strings like "1102&DEV_0004&SUBSYS_00011103&REV_04".

Under each of these folders will be another folder with a long numerical name.

Open each folder and look for the "DeviceDesc" which matches the hardware you are trying to install.

Right Click on the "VEN_xxxx" for that device and select 'Permissions' and then tick "Allow" for "Full Control". Close Regedit and then continue with the installation of your device.

I cannot guarantee it works for everyone, but although I swear by it after swearing at it(XP), it should help you if you ever had casual problem.
