Download the driver
for Vista from Creative website.
Extract the files from within the exe file (winrar)
Should be 3 files.
One is Setup.exe
Download Universal Extractor (search google)
Use Universal Extractor to extract the files from within Setup.exe.
Manually update the device driver, point to the folder with the extracted files from Setup.exe.
It worked for me, my creative live cam vista im vf0260 now works on windows 7 64bit.
