Sony DCR-TRV140 camcorder. USB connection to PC with Windows 7 64 bit. MIcrosoft's website says that the camcorder is supported under Windows 7 32 bit with no additional software but when I connect the camcorder to my PC there is no driver found and Device manager show a yelllow bang ( !).

To get your camcorder to work properly with your PC (and show up in Device Manager), you must install the software (the driver and editing software) that came with your camcorder. Your system also must meet the following minimum requirements: * CPU : Intel® Pentium III 450MHz processor compatible or better * Operating system : Windows® 98SE/ME/ 2000/XP * RAM : 128 MB or more * CD-ROM: 4x CD-ROM drive * VIDEO : 65,000-color or better video display card * Available USB port * Hard Disc : 4GB (8GB recommended) If the camcorder is still not being recognized after you have installed the software, reboot your computer, and then try another USB port or another USB cable. If your problem persists, contact Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864). Be sure to have the model number of your camcorder handy and basic information about your PC such as operating system, kind of CPU, and available memory.

I had a similar problem with my Sharp camorder.
The preview window on XP simply displays corrupted images.
At the end, I bought a different firewire card and it worked for me.

Good luck.

Hi -

Have you tried another USB port? Sometimes, they can act goofy.
Also be sure your anti-virus isn't blocking any part of the installation.

Here is a link to the Samsung troubleshooting guide for your camera.
You can probably download the most recent driver from that website as well.
Perhaps they have a better or newer version than what came prepackaged
with the camera (just because a camera is a new purchase does not mean
the software it came with is the most updated).

I run WinXP home edition, so I am not familiar if there are any differences in the professional version regarding software installation....

Good luck!

Try going into your control panel I JUST DID THIS!!!! because i had the same exact problem and it was killing me. Select your systems folder and click hardware you will see driver singing button click it and select "ignore install the software anyways" and that is it. it worked immediately after that simple change.
