======================================================================
VERSION 1.2.0+
======================================================================

If you used the InstallDrivers.exe that ships with version 1.2.0.0 and above
of the drivers initial uninstallation should first be done as follows:

   - Open control panel (start menu/Control Panel)
   - Select "Programs"/"uninstall a program" option 
     also referred to as "add/remove programs"
   - Locate the entry with the name 

     "Windows Driver Package - Starlight Xpress CCD Driver"

   - Click that entry and select uninstall. 
   - Confirm deletion of drivers

If problems persist, you can attempt the steps below to check for any other
versions of the drivers that may still be installed. Note, BlockIO.dll is
the name of the pre 1.2.0 drivers, SXCCD.dll is the name for the newer 1.2.0+
drivers. Attempt the steps looking for either entry depending on which version
of the drivers you have previously installed.

Manual Uninstall
======================================================================

Plug your camera in, open device manager and right click on the entry for your camera then select uninstall. If there's a check box to delete driver files, tick it then click ok.

Look in

   C:\Windows\System32\drivers\UMDF  (for 64bit)
   C:\Windows\SysWOW64\drivers\UMDF  (for 32bit)

for a file called SXCCD.dll and delete it if it still remains.

Unplug your camera.

Open a cmd prompt (type cmd into the start "search for programs and files", right click on the cmd.exe and run as administrator ) and run

   pnputil.exe -e | more

browse the list it returns for one that says 

  "Driver package provider : Starlight Xpress Ltd"
  "Class : Universal Serial Bus devices"

note the published name, such as oem12.inf (actual number will vary)

Now type,

  pnputil -f -d oem12.inf

(Be sure to use the correct oem number, 12 is just an example)

Repeat the above until you find no more entries.

Reboot.

======================================================================
PRIOR TO 1.2.0
======================================================================

The drivers prior to 1.2.0 used the name BlockIO, the steps are the same as the above manual unstall steps but with a different set of names to look for.

Plug your camera in, open device manager and right click on the entry for your camera then select uninstall. If there's a check box to delete driver files, tick it then click ok.

Look in

C:\Windows\System32\drivers\UMDF  (for 64bit)
C:\Windows\SysWOW64\drivers\UMDF  (for 32bit)

for a file called BlockIO.dll and delete it if it still remains.

Unplug your camera.

Open a cmd prompt (type cmd into the start "search for programs and files", right click on the cmd.exe and run as administrator )
Enter:
  pnputil.exe -e | more

browse the list it returns for one that says 

  "Driver package provider : FigmentGames"
  "Class : BlockIO"

note the published name, such as oem12.inf (actual number will vary

Now type,

  pnputil -f -d oem12.inf

(Be sure to use the correct oem number, 12 is just an example)

Repeat the above until you find no more BlockIO/FigmentGames entries.

Reboot.

Plugging your camera in now should show an ECHO2 device under Other devices. You should now be able to follow the normal driver installation instructions.
