Don't know if this will help-just part of a long list dl from apple. Good luck. jim George Booth wrote: Can anyone tell me what these errors are as I can't get my Quicken 2001 Deluxe to open because I get message "application has unexpectedly quit because of type 3 error" and sometimes says type 2 error. Type 1 and 2 errors Errors with a code of 1 or 2 are memory errors. Type 1 are bus errors and type 2 are address errors. Getting one of these errors means that the application is unable to address a segment of memory because that memory is either reserved for another use or doesn't exist. This can also appear as a type -110 error. Possible Solutions 1) Allocate more memory. At a minimum, you should use the preferred setting of memory for the application. Quit the application, find its icon on the desktop, and press {apple} -I to bring up the Get Info box. If you have any extra RAM, go ahead and allocate more than the suggested amount and see if that clears up the problem. 2) Delete an application's preference file. If you are experiencing problems with one application and can't seem to find the cause or the solution, quit the application, and remove that application's Preferences file from the System Folder's Preference folder. Afterwards, relaunch the application so it will start a new preferences file. You will need to reset any settings or preferences you've changed while customizing the application. 3) Look for extension conflicts. You can test for extension conflicts by the process of elimination. (disable half of your extensions by dragging them out of the Extensions folder, then restart to see if the problem disappears; continue subdividing until you locate the problem extension). You can also use the same technique using the Extensions Manager. 4) Reinstall software. If none of the previous steps have helped, try reinstalling the software. Afterwards, remember to trash it preferences as directed in Step 2. If you are still experiencing problems, try reinstalling your system software with the clean install option. 5) Check for viruses. It is important to regularly run a virus-detection program on your Mac. These programs can tell you if a virus is spotted on your computer and sometimes can repair the problem.
