APPLIES TO

Microsoft Office 97 Developer Edition

This article was previously published under Q201357

Moderate: Requires basic macro, coding, and interoperability skills.

SYMPTOMS

When you are installing a run-time application on a computer, you may receive the following error message:

Setup could not write to the file: 'C:\Windows\System\Wininet.dll'. This file is currently being used by another application. Close any open applications.

or

Setup could not write to the file: 'C:\Windows\System\Urlmon.dll'. This file is currently being used by another application. Close any open applications.

You then have the following options: Retry, Abort, and Ignore. The path to the files will be specific to your computer's Microsoft Windows System path.

CAUSE

The run-time application that you are installing contains a newer version of one or both of the files, Urlmon.dll or Wininet.dll. The Setup program always tries to overwrite older copies of files on a system that it is installing the files onto. The Setup program will not be able to successfully overwrite these files if the files are locked by the Windows operating system.

RESOLUTION

You can change the version of the Urlmon.dll and Wininet.dll files that are included in your disk images by changing an entry in two of the Setup Wizard tables.

For information about how to make these changes, see "Solution 3" in the following article:

MORE INFORMATION

At the time of this writing, if you click Ignore in the error message box, your application is successfully installed without any side effects to Microsoft Internet Explorer 4.0. However, Microsoft still recommends that you use the resolution described in the "Resolutions" section to resolve the error message completely.
