I have been using ViewNX for the longest time and though loading times for preview of images was slow at times I was very happy with my ver. 1.3. The other day I updated to ver 1.5, and after the update everything was running much faster. Then today it refuses to open and I get a "The application ViewNX quit unexpectedly" even before it opens. The report is as follows: Process: ViewNX [362] Path: /Applications/Nikon Software/ViewNX/ViewNX.app/Contents/MacOS/ViewNX Identifier: jp.co.nikon.ViewNX Version: 1.3.0 (1.3.0.3000) Code Type: X86 (Native) Parent Process: launchd [71] Interval Since Last Report: 3534 sec Crashes Since Last Report: 2 Per-App Interval Since Last Report: 9 sec Per-App Crashes Since Last Report: 2 Date/Time: 2009-10-30 22:36:10.862 +0800 OS Version: Mac OS X 10.5.8 (9L30) Report Version: 6 Anonymous UUID: FEB81E96-DAAB-4EF6-84C0-14C10C1B2EE8 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000013cea744 I tried all the suggestions I can find on the net to no avail, here is what I have done so far: 1. repair permission, reset PRAM 2. delete app through appcleaner, repair permission, re-installed 3. same as #2 but re-installed ver 1.4 4. same as #2 but re-installed ver 1.3 5. delete app through appcleaner, remove all nikon files in /user/library/preferences, repair permission, re-installed ver 1.3 6. same as #5 but instead of re-installing, used time machine to restore ver 1.3 from before ver 1.5 update All of these have failed, I have not installed anything new nor made any update to my computer.
