For 20+ years I have run quicken with my quicken file hosted on a Windows Network Share. It has worked flawlessly. The network folder is mounted on a physical RAID-1 disc giving me a level of security against physical disc failure that cannot be obtained any other way. For additional security no other software, other than the OS is installed on the Network Server, and it locked down tight. Starting with the November Update I have been unable to open my Quicken file. I have seen quicken warnings that they are not designed to run on a network share in the past, but it seems they now refuse to run. Rolling back to the October patch fixes the problem.
