You may receive the following error message when you run Detect and Repair for Office 2000:
Microsoft Office 2000 SR-1 Professional Error 1931: The Windows Installer service cannot update the system file C:\Program Files\Common Files\Microsoft Shared\VGX\Vgx.dll because the file is protected by Windows. You may need to update your operating system for this program to work correctly.
NOTE:You can run Detect and Repair for Office 2000 with either of the following steps:
  • Click Detect and Repair on the Help menu in an Office 2000 program.
  • Click Repair Office for a Microsoft Office product from Add/Remove Programs.
This problem may occur if you have Microsoft Internet Explorer 5.5, 5.5 Service Pack 1 (SP1), or 5.5 Service Pack 2 (SP2) installed. The version of the Vector Graphics Extensions (Vgx.dll) file that is included with these versions of Internet Explorer has the wrong checksum and is reported as a beta version. For example, the incorrect version of the Vgx.dll file that is installed by Internet Explorer 5.5 is:
Vgx.dll, version 5.50.4133.200 BetaVersion BETA, Office Version 10.0.803
The invalid checksum causes Microsoft Installer to determine that the file is damaged and must be restored.On operating systems that do not support the System File Protection feature, the following Office version of the Vgx.dll file is installed by the Detect and Repair process from the CD-ROM or from the Microsoft Office Web site:
Vgx.dll, version 5.00.3014.1003, product version 5.00.3014.1003
To resolve or work around this problem, use one of the following methods.

Method 1

Click OK in the error message dialog box to close the dialog box. Detect and Repair will continue to run normally.

Method 2

To prevent this error message from appearing, upgrade to Microsoft Internet Explorer 6.0 or later.

Installing this fix on a version of Internet Explorer other than 5.50.4807.2300 has not been tested by Microsoft and is not supported. You may experience other problems in Internet Explorer or Windows if you install a fix that was not designed for your specific version of Internet Explorer.
