I Bought a Vivicam35 n1659 camera from Wal-Mart and lost the installation disk. I tried downloading the other drivers listed on this site and the zip files where Courrupted or Invalid.
I registered the camera on Vivitar's site, they didn't list it under support but it was listed in the products available for registration they told this:
Email us at firstname.lastname@example.org and request a driver for a vivicam35 and we will send you the driver via email.
I did and this is what I got. If you experience this same problem, I suggest you do what I did and register your camera and then e-mail email@example.com for the driver they are fairly quick to respond, less than 24 hours to respond to me and get my driver.
The following files are found inside the driver download file.
