Anyone who has experienced a problem trying to backup Vista or 7 32/64 and received an "app error message", I have discovered that Windows Vista/7 System Restore must be activated. I use a Sold State Drive and disabled all Write Catching, Page Files and System Restore to give my SSD a longer and fast response lifetime. After repeatedly receiving the error during backup, I enabled Windows System Restore but just 1% of my SSD. I kept the other two items disabled. Voila! PHDM 2012 works great now. BUT, this poses the question to the developers. Those of us with SSD do not want excessive writes to our drives. Will PHDM 2012 and future version require that System Restore be enabled? Thanks in advance for your help.
