'data is invalid' when installing PCI cards

[jacobsmichael]

Hi,

I'm putting together a P4 system with a Tyan Trinity i845 S2090 board. Got an error that I've never come across before. Upon trying to install any PCI card (multiple cards, any slot), the windows installer gets an error upon trying to install the card (prior to prompting for a driver). Error is 'Unable to install ..., Data is invalid'. Has anyone seen this before? I found some XP reference to changing permissions settings for the particular hardware key, but it doesn't look like I have that option in the 2000 registry.

Any help would be greatly appreciated.

Thanks
Michael

Replying to my own post, but here is the info I found relating to XP for what sounds like a similar problem. Can't see any option in the 2000 registry to change permissions on keys though....

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_MACHINESYSTEMCurrentControlSetENUMPCI

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.
