WASServiceMsg.dll is locked when installing WebSphere Fix Packs and cumulative fixes on Windows

Troubleshooting


Problem

The WASServiceMsg.dll file is locked by the Microsoft Windows operating system and cannot be updated during the upgrade of WebSphere Application Server.

Symptom

If the WebSphere Application Server is defined as a service on Microsoft Windows, the following errors can occur during installation or removal of the WebSphere software.

Unable to open destination file: <path>\WASServiceMsg.dll 
Failed to delete: <path>\WASServiceMsg.dll

During an uninstall or fix pack installation, the WASServiceMsg.dll file can be in use by some non-WebSphere code such as the Windows event viewer. If the module is loaded in memory, the file cannot be removed or replaced. The uninstall or installation process fails.
