In most cases, Software Installation policy can encounter problems due to:
Software Installation extension problems.
Group Policy processing errors.
Windows Installer errors.
This section shows how you can troubleshoot these issues using log files and other diagnostic tools. The section concludes with common issues and troubleshooting checklists.
Event Log
All major errors encountered by software installation are written to the Application Event Log. Check the Event Log for any warnings or errors from “Application Management” to see detailed information about any failures.
Also check for errors from Userenv and MsiInstaller logs that might be related to the problem you are seeing with Software Installation.
Errors from Userenv indicate a problem with Group Policy in general that may result in Software Installation policy not being applied to the user or computer. For information on diagnosing Group Policy errors, see “Solving Common Problems in Group Policy” earlier in this document.
Errors from MsiInstaller are written by Windows Installer and may indicate a failure in installing the deployed application. For example, when users click on an advertised shortcut created because of an application assigned to them, the install may fail due to low disk space or a problem accessing the software distribution point over the network. In this case, a relevant error from MsiInstaller in the Event Log should provide information about why the install failed.
