If you get the error "The data is invalid" while installing a new modem into your system, you can resolve the error by following these steps.
Click "Start" and select "Run".
Type in "regedit" in the open field and click "OK".
The Registry Editor will then appear on the screen
Click on the (+) icon next to the word "HKEY_LOCAL_MACHINE"
Click on the (+) icon next to the word "SYSTEM"
Click on the (+) icon next to the word "CurrentControlSet"
Click on the (+) icon next to the word "Enum"
Click on the (+) icon next to the word "PCI"
Inside the "PCI" folder there are keys like this :
(VEN_1471&DEV_0188&SUBSYS_5004144F&REV_10)
Each of these keys represent a device installed in your PC. You need to go through all of these keys one at a time.
Click on the (+) icon next to the first key and then a subkey will appear below it like this:
3&13c0b0c5&0&10
Click on this key and on the right hand side there will be a value called "DEVICEDESC"
Search through all of the "DEVICEDESC" values for each key. You need to match the "DEVICEDESC" value with the type of device you are installing.
For ADSL Modems this will read "Network Controller". For PCI Modems this will read "PCI Communications Device". For example if the device you are trying to install is an ADSL modem then the "DEVICEDESC" would be "Network Controller". Or, if the device you are trying to install is a PCI modem then the "DEVICEDESC" would be "PCI Communications Device".
Once you have searched through each of the keys and found the correct "DEVICEDESC" right click on it, and select "Permissions".
Place a tick in the box under the word "Allow", next to "Full Control".
Click on "OK"
Close the Registry Editor.
Click on "Start", then select "Control Panel".
Open the "System" control panel.
Select the "Hardware" tab.
Click the "Device Manager" button.
Look for the "Other Devices" heading and click on the (+) symbol next to it.
Right click on the device name that matches the "DEVICEDESC" value you changed in the registry and select "Properties".
Click on the "Driver" tab at the top of the screen
Click the word "Update Driver". Windows will now ask you for the disk or CD-ROM that contains the driver for the failing device.
Once you insert the media and point it to the correct location then the device will now install itself correctly without any errors.
