I know Adobe does not yet officially support Lightroom 1.0 installed on a computer running Windows Vista. But, I'm curious to know if anyone out there has tried this, and if there are any problems.
I had the same question; here's what I found on the good "FAQ" put together by lightroomextra.com:
Windows Vista Compatibility.
Windows Vista is a brand new operating system from Microsoft and has not been available in its final form long enough for Adobe to fully certify Lightroom for use on Vista. Adobe is working hard to finalize support or Vista as quickly as possible and will deliver appropriate software updates over the launch period. Lightroom 1.0 will install and run on Windows Vista but Adobe cannot guarantee the quality of the software experience until final testing is completed.
Known issues for using Lightroom 1.0 on the Vista operating system are listed below:
Lightroom CD and DVD burning tools will not currently function
Importing files directly from a Camera or Card Reader may not function properly. Please copy files to a local hard drive via the operating system before importing the files into Lightroom.
