I went to download the photosynth uploader from this link that has been given on other threads for Windows 8 CP (http://photosynth.net/installer/photosynthinstall.exe) but this link appears to be dead. Is there any new link for this?
OK, no worries - I fixed it the old fashioned way... Downloaded the install file on my Win7 laptop and installed it on my Win8 desktop.... worked like a charm - if a little annoying to have to do that...
Try this link on Windows 8:
It's working for me.
