I am running a UK version of Quicken personal financial software (Quicken XG 2004 UK) on my computer with XP SP3. I regularly save a backup copy of the Quicken file to a second hard disk and a USB stick. Since installing Nod v5 RC (AV, not ESS) I have been unable to back-up the Quicken file to either the second disk or the USB stick, or indeed any other location on my PC or removable media. When I attempt to save a back-up copy Quicken displays the error "Unable to access the disk in drive X:" (where X is the drive letter for whichever destination I have chosen). It's taken me a while to track the problem down because I installed the Nod RC on the same day as the latest Windows patches, but I have now found that Quicken behaves normally after I disable HIPS and reboot the machine. The problem didn't occur with HIPS enabled in the previous v5 beta, so I can only assume something has changed with HIPS between the beta and RC. I have also installed Quicken on a laptop also running XP SP3 patched with the latest Windows updates, but with my licensed Nod v4 installed, and again the problem doesn't arise, so I assume from this that it points to an incompatibility between the program and HIPS. Quicken is no longer sold or supported in the UK and the version I am running was the last available version. I have so many years worth of records invested in it that I would like to keep it running if possible. I should also mention that Quicken has to be run with admin privileges, but I normally run it as such from a limited user account, although whilst testing this issue I have run it both in that way and whilst logged in as an administrator, with identical results. Any ideas gratefully received. Do I need to create a rule in HIPS, or am I resigned to running Nod with HIPS disabled?
