Windows Installer is a service in operating systems from Microsoft Windows XP and later. It is used in both software installs and uninstalls, as well as software maintenance. Microsoft encourages all software developers to utilize Windows Installer as the basis for their software installation packages to ensure smooth installs, updates and uninstalls. Windows Installer errors may occur due to damaged or missing files, corrupt registry keys or the installer files not being properly registered in the Windows registry. Software that has been uninstalled from the system may leave traces and shortcuts behind in Windows Installer, which may in turn lead to more errors. Cleaning Windows Installer helps prevent errors from occurring and promotes stable future installs and uninstalls.
Windows Installer errors can be fixed and prevented with special software that repairs the registry and tunes up system settings.
The article provides details on the symptoms, causes and ways to clean Windows Installer and repair related errors.
Symptoms of Windows Installer errors
The main symptom of a Windows Installer error is a failed installation or uninstallation of a software application, which often brings up a message that reads something similar to the following: "Windows Installer service could not be accessed", but other error messages are also possible. The error log that gets created when the error occurs may contain additional information that can help an IT professional locate the source of the problem and get it repaired.
Causes of Windows Installer errors
Windows Installer errors are typically caused by missing or damaged installer files or corrupt registry entries related to the Windows Installer service. The Windows Installer service not being properly registered in the Windows registry is another common reason for this error type.
Incomplete software uninstalls may leave traces in Windows Installer and cause various errors in the service.
Ways to clean Windows Installer and repair errors
