If you're using a USB camera, there's a good chance that you installed a driver on the first PC.

Have a look at the Troubleshooting USB Camera Installations page. 

The driver can be found here.   http://zone.ni.com/devzone/cda/epd/p/id/5030

thank You very much!

This is the solution of problem:

Solution:
To run an EXE containing NI-IMAQ for USB functions, complete the following steps on the computer running the EXE:

1. Install the following run-time engines:
   • LabVIEW Run-time Engine (same version that was used to develop the VI)
   • Vision Run-time Engine (same version that was used to develop the VI)
     • A single-seat Vision Deployment License is required for each target machine on which you install the Vision Run-time Engine. See Related Links for more details.
   
   
2. Copy the following DLLs from your development machine's System Directory, typically C:\Windows\system32, to your target machine's System Directory.
   
   • ImaqDirectShowDll.dll
   • ImaqDirectShowExport.dll
   
   
3. Register ImaqDirectShowExport.dll by selecting the Windows Start Menu and selecting Run. Type in regsvr32 C:\WINDOWS\system32\ImaqDirectShowExport.dll and click OK to register the DLL.
   
   If you are on a different OS or if the system directory is different and you want to copy the file path instead of typing the whole path, you can drag the file to the command line in the Run prompt, highlight the path, right-click and select Copy.  Paste in the command prompt window by right-clicking and selecting Paste.
   
   The ImaqDirectShowDll does not have to be registered.
   

Once these steps are completed and the DLL is registered successfully, your EXE will work.  Neither Vision Acquisition Software nor Vision Development Module needs to be installed on the target computer.

Does this method also work for Windows 7 and 64 bit OS?

We followed this solution for 64 bit OS, but found an erro.

Thanks.

So...what's the solution for my "64 bit" Win 7?

Could anyone answer me?

Thanks a lot~~
