I think it is possible that my current driver is corrupt.

How do I go about removing all track IR software including registry entires and doing a fresh clean install?

Many thanks.

In the registry we need to make the following changes:
NOTE: Be sure to remove any entries in "Add/Remove Programs" for the TrackIR software.

1. Removing the USB ID's for the TrackIR in the registry and any multiple copies. You can access the registry by
doing the following:

A. Click "Start" then "Run".
B. Type: "Regedt32" and press "Enter".
C. When it's loaded be sure to give yourself "Full Control" permissions for "HKEY_LOCAL_MACHINE". You
can do this by right-clicking on it.

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00x\Enum\USB
NOTE: The above might have multiple entries where "ControlSet00x" might be "001" and "002" and so on.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB

All of these braches needs the following entries removed:

- Vid_131d&Pid_0155
- vid_131d&pid_0150
- VID_0547&PID_1002

NOTE: Please let me know which of these where found.

2. We also need to remove our USB driver services. There also may be multiple copies as well.
"NPUSB" is what you would want to delete.

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00x\Services\NPUSB
NOTE: The above might have multiple entries where "ControlSet00x" might be "001" and "002" and so on.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NPUSB

3. Also delete any entries that have this string:

- 5&206F11E9&0&2

That's the extent we need deleted from the registry.

4. Now we need the following files deleted from the C:\Windows\INF folder.

- NPUSB3.INF
- NPUSB3.PNF

The following file is located in: C:\WINNT\system32\drivers
- NPUSB.SYS

5. Now we can install the current drivers for the TrackIR. Link is below for convenience.
NOTE: Do not connect the TrackIR before installing this software!

After the software is installed reconnect the TrackIR and it should allow the driver to be installed
Properly this time into the "Device Manager".

Thanks for your response Vincent.

Removed all Track IR components via Add/Remove.

Under control set 001 and 003 I found entries for -vid_131d&pid_0155. When I tried to delete them I got a message
"Cannot delete vid_131d&pid_o155. Error while deleting key.

Was able to delete the NPUSB entries in both control sets.

Could not find any entries with 5&206F11E9&0&2

Could not find C:\Windows\INF folder

Did a search for NPUSB3.INF and NPUSB3.PNF but could not locate

Deleted C:\Win\System32\drivers\NPUSB.SYS

Reinstalled Final1.exe

Rebooted.

Connected Track IR 3 camera

Searched for drivers and appeared to install ok but got an error message saying error and hardware might not work. No lights came on in unit and it would not function. Repeated above steps three times with no success.

Took unit to a back-up computer where it worked perfectly.

Did a Windows XP reformat 2 weeks ago on my primary computer.

What was the exact error message?

Do you mean this error message?

If you highlight the registry key, right click, and go to permissions. Is your login listed here?

My goodness Vincent. Don't you ever sleep?

I did as you said and was finally able to delete the two entries. I had to change the permissions to full control.

I am pleased to report that my Track IR 3 Pro is working again the way it should, thanks to you.

This has been a most worthwhile exercise.

Appreciate your help m8.

No issues, and enjoy!!!!

and nope, I never sleep
