some downloads (and purchased software) cannot be opened. When I attempt to load from CD Rom I get the message 'could not be opened. System Profiler cannot open files in System Profiler Document format'
Same software will load on another Mac Mini but not mine. It will not allow me to open it in a new folder - Any Ideas please ?
Disk utility repir permission facility made quite a lot of changes. unfortunately the problem remains and the Profiler Icon pops up in the docking bar. I have tried the software on a similar machine (Mac Mini G4 125 ghz) with no problems at all. Thanks for the suggestion.
It seems that OS X has "decided" that the default program for installing is Apple System Profiler. Sometimes this is fixed by repairing permissions, but not always, as in your case.
It is possible to "tell" OS X which program to use, but the problem is is that there are a number of different installer programs. Apple software as well as quite a few other programs use Apple's installer.app. So, pick one of the non-opening installers & highlight it in the Finder, highlight it & choose Get Info from the File menu. In the Get Info box, click the triangle next to "Open With." If it says System Profiler, click on this drop-down menu & choose Installer.app. If this is not a choice, choose "Other" & navigate to the Installer.app located in HD > Applications > Utilities. Now try to install that program works, repeat the process on another installer & click the "Change" button under the text that asks if you want to open all documents like this with Installer.app.
