I followed Pandlouk's instructions to the letter (thanks!) and happily had a working set up with Win 7 (x64) & Win XP (x86) in different FD-ISR snapshots but although XP snapshots are working well & copy/ update without problems there are major issues with the win 7 snapshots. All Win 7 snapshots boot well and behave normally but when copying/ updating both snapshots & archives FD-ISR freezes for up to 5 minutes during the Preparing to Copy/ Indexing stage usually around the time indexing gets to around 3800 files. Win 7 snaphots are all x64, all do not yet yet have AV/ Firewalls/ HIPS but have other programs installed. I've tried to see if any of these could be the cause of the problem but there doesn't seem to be a definite culprit. I wondered whether it was a conflict with Windows Search in 7 and tried disabling that but problem of 'freezing' continues. Has anybody else had similar problems or can suggest a solution/ new way forward?
