U-PAD2 A/D Converter
5 Troubleshooting
5.3.2 Reinstallation of drivers in Windows 2000
Note:
Windows
2000
is supported until
Clarity
version
3.0
only.
After installing
Clarity
and the
U-PAD2
device, the
Device Manager
either
does not display the
Chromatography Devices – U-PAD2
item at all or it
displays a yellow exclamation mark next to the item that indicates that the
device is not working properly.
Fig 28: Device Manager in Windows 2000
If the "
U- PAD 2.0 (DataApex)
" item is missing,
Windows
has
automatically installed incorrect driver.
If you are able to locate which device was mistakenly installed instead of
the
U-PAD2
driver, you can open its
Properties
and
Update this driver
. In
the manual installation process, select the correct drivers analogically to
the description in the chapter
"Installing the correct driver manually"
If the correct driver cannot be determined, the last installed driver will have
to be removed.
Caution:
This procedure can be used safely only if you did not install any other
hardware since the installation of the converter.
5.3.2.1 Deleting incorrect *.INF files in the system
Note:
Be sure to have the
Clarity
software already installed.
Open the C:\WINNT\INF ( C:\WINDOWS\INF ) folder
①
in
Windows
Explorer
.
Note:
You may have to allow for the hidden system files to be displayed. In menu
select
Tools - Folder Options - View
tab then set the
Hidden Files and
Folders
option to
Show Hidden Files and Folders
.
