Remove Improperly Installed Files
►
Procedure
1. Open Windows Explorer.
2. Navigate to the Windows | INF directory.
Note
If the INF directory is not visible, you must disable the Hide System Files and Folders
and Hide File Extensions for Known File Types options in Windows Folder Options.
Access Windows Folder Options from Windows Explorer, under the Tools | Folder
Options menu selection.
3. Delete the OOI_USB.INF in the INF directory. If your computer is running either the Windows
2000 or XP operating system, you must also delete the OOI_USB.PNF file in the INF directory.
4. Navigate to the Windows | System32 | Drivers directory.
5. Delete the EZUSB.SYS file.
6. Reinstall your Ocean Optics application and reboot the system when prompted.
7. Plug in the USB device.
The system is now able to locate and install the correct drivers for the USB device.
Mac Operating Systems
Since there are no device files for the Apex Spectrometer in a Mac operating system, you should not
encounter any problems if you installed the spectrometer before the operating software.
Linux Operating Systems
For Linux operating systems, all you need to do is install the software, then unplug and replug in the
spectrometer. Technically, the driver files for Linux simply give nonprivileged users permission to use
newly connected hardware. There isn’t any long-term harm to plugging in the device before installing the
software.
