看看这个行不行，呵呵
The following procedure will remove the National Instrument Software:
1. Turn off the computer and physically remove or unplug all NI hardware that you have installed on your system. This includes anything that is PCI-, ISA-, USB-, 1394-, or ethernet-based.
2. Turn the computer on and go through Add/Remove Programs (START » SETTINGS » CONTROL PANEL » Add/Remove Programs) and remove everything NI-related. Generally, if you can remember, it is best to uninstall things in the reverse order in which they were installed. For example, if you installed LabVIEW, then NI-DAQ, and then the Internet Developers Toolkit for LabVIEW, you should uninstall the Internet Developers Toolkit first, then NI-DAQ, and then LabVIEW last.
3. After everything has been removed (do not be concerned at this point if an item still shows up in the Add/Remove Programs list after you have removed it), close all programs and restart your computer.
4. Go to START button of your operating system, choose RUN and type "regedit". This will open the Registry Editor window. Go to the Registry Menu and choose Export Registry File. Select "All" for the export range, and select a file name. This creates a backup of the Registry in case a mistake is made when deleting the keys.
5. Remove the following registry components from the Windows Registry:
HKEY_CURRENT_USER\Software\National Instruments Delete the entire tree!
HKEY_LOCAL_MACHINE\Software\National Instruments Delete the entire tree!
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Enum\PCI\ or \ISA and delete registry entries containing any keys with 1093 in them.
Do not worry if any of these trees are not listed. Continue with the remainder of the process .
Note: You may need to modify security policies. In Windows 2000/98/95/NT, go to [regedt32] then Security>> Permissions. In Windows XP you can modify security options using Edit>> Permissions in the Registry Editor (regedit).
6. Close regedit.
7. Make sure that you do not have any of your own VIs or other files saved in the "C:\VXIpnp", "C:\Program Files\National Instruments", or "C:\WINDOWS\nidaq" folders. If you do, copy them to a different location. If you are concerned about keeping old virtual channels and your SCXI setup intact, then backup the "C:\WINDOWS\niconfig.daq" file, too. Delete all folders and files mentioned above.
Note: If you have Windows NT/2000, replace "C:\Windows" with "C:\WINNT" in the paths listed above.
8. Download the Windows Installer Cleanup Utility (msicuu.zip file attached) and copy it to the hard drive.
There are two versions of the Windows Installer Cleanup Utility included in the zip file. The first version, Msicu.exe, supports Windows 95/98. The second version, Msicuu.exe, supports Windows NT/2000/XP. For more information and downloading instructions regarding the Windows Cleanup Utility, refer to Microsoft's website.
9. Run the windows installer clean up utility by unzipping the file and selecting the appropriate executable.
10. Reboot your computer.
11. You should be ready to install your software. For the cleanest possible install, first install all of your application development software, such as LabVIEW, Measurement Studio, etc. Do a custom install, so that you can install just the application WITHOUT ANY DRIVERS. Reboot your PC when requested after each install. Even if the installer does not tell you to reboot, it would probably be a good idea to do so anyway. Now install your driver software and follow the associated user manuals. Some older non Plug-n-Play hardware must be installed before the driver. Download the latest versions of the drivers that support your hardware from our Drivers and Updates software library (link below), and install them one-by-one, rebooting after each install.

12. Finally, shut down and re-install your hardware. When you boot back up, it should be detected in MAX.
