OMI 2.3.1 Release Notes 33
Installing Adobe Acrobat Software
OMI documentation is delivered in Adobe Acrobat format on the OMI installation
CD-ROM. If you have not already installed the Adobe Acrobat Reader software, you can
install it as follows:
1. Double click the rs405eng.exe icon within the \Acrobat folder on the OMI
installation CD-ROM.
2. Follow the on-screen prompts.
Uninstalling OMI Software
To uninstall OMI software, use the Add/Remove Programs control panel. The
application to remove is named Cognex OMI <version>.
If you are using Windows 98 or Windows 2000, you must remove the hardware as well
as the software, but you do not need to use the Add/Remove Hardware control panel
(unless you had the Plug and Play wizard install the drivers under Windows 2000, in
which case the OMI uninstall program will not remove the drivers).
Note The installer requests that you restart your Windows system after
uninstalling OMI. If you attempt to re-install OMI without first
restarting your system, the installer will not allow the installation to
proceed.
Caution Do not cancel an uninstallation when the system prompts you to
confirm the uninstallation. If you cancel the uninstallation, your
system might be left in an inconsistent state.
Uninstalling Windows 2000 Drivers
After uninstalling OMI from a Windows 2000 system, make sure that the MVS-8100 driver
files were removed.
1. Check whether the following driver files were removed by the uninstallation:
• MVS-8100 driver
\winnt\system32\drivers\v8100.sys
If these drivers were not removed, uninstall them as follows:
2. Search within the \winnt directory for all files ending in .inf that contain the string
"Cognex" in their contents. You can use the Search command in the Start menu to
do this. Delete these files and any similarly named files that end in .pnf. For
example, if you find the string "Cognex" in the file foo.inf, you would also delete the
file foo.pnf if it exists.
