TRDB-D5M not working with DE2-70 board

Hi,

I've just received my development board, DE2-70, with TRDB D5M camera.

First, in order to try the control panel software, I couldn't upload it to the Dev. board.

Only got it working by removing the Modelsim software, and restart.

Then, now, I'm going to test the DE2_70_CAMERA.exe application software that comes with the cd to test the camera.

But, when I'm going to upload the code, after 100%, and after few seconds, it said " Execute (....NiosDownloadBatch.bat) fail, Exitcode: 1H."

and 2nd warning, "Download Nios2 file (DE2_70_CAMERA.elf) fail! "

I tried to burn the DE2_70_CAMERA to the fpga using quartus programmer, and after I open the DE2_70_CAMERA.exe application, it's connected. but no pic at all.

If I click capture, it will pop up " Camera Capture Fail ".

By the way, I've already tried copying the jtag_client.dll and dinkum_alt.dll to the 'SW" folder. And also have tried to change the environment path to point the bin at the quartus file. But still not working.

Any Ideas?
