After setup iCloud, Photostream works fineon my iPhone/iPad. However, Photostream is not syncing on my Windows 7 PC. I place photos in Photostream upload folder and them don’t upload to iCloud. There are also no photos loading from my photostream to comptuer. Try reinstalling iCloud desktop program and disable virus scanner, but still not working.
