Problem: when clicking on the blue File Attribute link to open a Word Document, the error "The system cannot find the file specified." is displayed and MS Word does not open, even though MS Word is installed on the computer.
Solution: this error might occur if the Windows Operating System cannot find the WinWord.exe file on your computer, needed to start Word.
Do the following checks to verify this problem:
Check 1) Click the Windows Button + R to open a Run window. Type "WINWORD.EXE" in the text field in the Run window and click OK. If MS Word does not start, then this is another indication that Windows cannot find the WinWord.exe file.
Check 2) Click the Windows Button + R to open a Run window. Type "regedit" in the text field in the Run window and click OK. This will open the Registry Editor. Navigate to the path "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Winword.exe". If this location does not contain 4 entries (but only an empty string), then this is another indication that Windows cannot find the WinWord.exe file.
To find where MS Word is installed on the computer, open the start menu and find the Word icon. Right-click on the word icon and select "Open File Location" or More => Open File Location in the context menu. This will open the file location of the Word shortcut. Right-click on the word shortcut and select "Properties" in the context menu. In the Shortcut tab page, find the Target text field which contains the path to the WinWord.exe.
Use this win word exe path to update the Registry for the registry path defined above, using the following pattern:

If a VSTO customization cannot be uninstalled with the regular Control Panel - Apps & Features dialog, then access the "old" Programs and Features Dialog by clicking "Programs and Features" under the section "Related Settings" in the Apps & Feature dialog of the Control Panel. In this dialog, the VSTO customization can be uninstalled.
