Tips for resolving the error code 1605 in Windows.
WARNING! This Fix Requires a moderate amount of computer knowledge, if you do not believe you have the knowledge call your Technician. To resolve this issue, determine which template causes the issue, and then delete that template from the Word startup folder. To determine which template causes the issue, remove each template from the Word startup folder, and then test by trying to start Word. To do this, quit any running programs. In Windows Explorer, click Folder Options on the Tools menu. Click the View tab, click to select the Show hidden files and folders check box, and then click OK. Locate the drive:\Documents and Settings\username\Application Data\Microsoft\Word\Startup folder, where drive refers to the drive that Windows is installed on and username refers to your user name. On the File menu, point to New, and then click Folder. Type Temp, and then press ENTER. Click the first template that is listed in the Startup folder, and then cut and paste it to the Temp folder. Try to start Word. If Word starts successfully, you have removed the conflicting template. If you receive an error message, attempt the process with the next template, until Word starts successfully. After you have determined which template causes the conflict, cut and paste all the non-conflicting templates from the Temp folder back to the Startup folder. Click the Temp folder, and then press DELETE.
