If these files are damaged, it is possible that Prism simply wouldn't start. If it can't find a Prism preferences file, it tries to import preferences from a previous version of Prism. When Prism launches it opens the preference file to obtain your preference settings, user-define equations, list of recent files, color schemes, etc. Applications/Prism 6.app: satisfies its Designated Requirement?

Prism Windows, however, can only handle 258 characters. Windows allows up to 259 characters in the path that defines the folders, subfolders and file name.

The presence of several Library folders is potentially confusing, so make sure you are looking in the right one - the one within a particular User's library folder. Library/Application Support/GraphPad/Prism/6 Users/Library/Application Support/GraphPad/Prism/6/Prism Backupsĭon't confuse it with a similarly named path, which won't contain a Prism Backups folder. Note that the squiggle in front of that path tells you to look within the user's folder. Then empty the trash just to make sure it is gone.

OTHER SIMPLE FIXES THAT MAY SOLVE THE PROBLEM Make sure you are not running an old version of Prism with a new version of OS X If you see a message similar to "only power users may install software" or "access denied," or "you are not authorized to perform this action" or "only Administrators may install prism" or "unable to save serial number file" then switch to this FAQ. Be sure to choose your hard drive, not the program CD or DMG 'drive'. Once inside the Disk Utility window, select the System disk, then go to the First Aid tab and then click the Repair Disk Permissions button. ![]() Run the Disk Utility located at: ":Applications:Utilities:Disk Utility".The steps explained below should be done routinely on a Mac (especially one running an older version of OS X) when things aren't working well. THE SECOND THING TO TRY: Repair disk permissionsĭisk permissions problems are common in Macs, but easy to fix. If using El Capitan, see this faq about a rare problem and how to bypass it.Make sure you have the latest Prism update.The first three items listed here will probably solve the problem.
