"Cannot Install the Necessary Files Due to Windows Installer Error 1605"
Error Message When You Try to Start Word
SYMPTOMS
When you try to start Microsoft Office Word 2003, you may receive the
following error message:
Microsoft Word cannot install the necessary files due to Windows Installer
Error 1605
Word does not start.
CAUSE
This issue may occur if there is a problem with a template in the Word
Startup folder.
RESOLUTION
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, follow these
steps:
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
move 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, repeat steps 5 through 7 until Word starts
successfully.
After you have determined which template causes the conflict, move all the
non-conflicting templates from the Temp folder to the Startup folder.
Click the Temp folder, and then press DELETE.
