Installing multiple years of QuickBooks Desktop out of chronological order causes the Previously Opened File menu to be blank. Browsing to the file previously opened in that newer year version may return an error that it was last opened in Enterprise Solutions and cannot be opened in QuickBooks Premier. Trying to open that file in Enterprise, prompts you with the warning to make a backup before upgrading the file to Enterprise and that it cannot be opened in previous version.
