There are several different error messages you may receive when you start or attempt to start Word 2007 or a Word 2007. These errors may include Run-Time Error, Word Cannot Open This Document Template or Command Cannot Be Performed Because a Dialog Box Is Open.
When you are troubleshooting an error when starting Word 2007, make sure there are no open dialog boxes in instances of Word already running. For example, if you have working in another Word document that you are trying to print and the Print dialog box is open, you may see an error message if you attempt to open a second Word document.
If there are any dialog boxes open, close them and try to open the Word document again. If there are no dialog boxes in use, further troubleshooting is necessary. Close Microsoft Word and any other Microsoft Office applications such as Outlook or Excel. Go to the Start menu and open Computer or My Computer. Double click your main drive, which is probably Local Disk (C:). Open the Program Files folder, then the Microsoft Office folder. Find and open Office 12 and then the Startup folder. If there are any files in the Startup folder, drag them or cut and paste them to the desktop. Close the Startup folder and open Microsoft Word 2007.
If you still see an error, continue to this troubleshooting step. If you are using Windows XP or earlier, open the main drive, which is probably Local Disk (C:). Open Documents and Settings and double click the username you are using. Open the Application Data folder, double click Microsoft, open Word and then open the Startup folder.
If you are using Windows Vista, click the Start button and type appdata into the Start Search box. Click the appdata folder in the search results. Open the Roaming folder, open Microsoft, double click Word and then open the Startup folder.
Drag or cut and paste any documents in the Startup folder to the desktop. Close the folder and start Word again.
