Vivitar vivicam 55

I lost my disk to my vivitar vivicam 55 are there any where on the computer that you can down load the software to be able to use my camera with my computer can you help please

I got the setup program from DriverGuide. It's not installing for me though. It says I need to be signed in as "Administrator" to change some files. Thing is, I am signed in as admin. So if anyone knows where to get just the .inf please pass it along.

If your computer is a Windows ME/2000/XP/Vista

You do not need any extra  software.
Simple plug the camera into the USB socket
switch camera on ensure it is set to upload
And Windows will do the rest.

Explain how i get 2 the upload screen on the cam vivicam 55
