The Prerequisite Checker (prereqchk.exe) is a standalone application that verifies server readiness for a site server or specific site system roles. Before site installation, Setup runs the Prerequisite Checker. You might choose to manually run the Prerequisite Checker on potential site servers or site systems to verify server readiness. This allows you to remediate any issues that you find before you run Setup. The Prerequisite Checker notifies you of any warnings or errors encountered that would cause Setup to fail. Tests that result in a warning do not prevent you from successfully installing Configuration Manager. However, resolving the condition that generated the warnings now might prevent issues later and helps to ensure optimum site performance. Tests that result in an error prevent you from completing the setup process and you must resolve the condition that generated the error.
 Note |
|---|
| The Configuration Manager Setup prerequisite check rules verify that software and settings required for setup are installed. In some cases, the required software itself might require additional software updates not verified by Configuration Manager Setup. Before you start Setup, verify that the operating system running on the computer, and additional installed software that Configuration Manager Setup relies on, have been updated with all relevant software updates. |
 Tip |
|---|
| When the prerequisite check runs, it logs its results in the ConfigMgrPrereq.log file on the system drive of computer. The log file can contain additional information that does not display in user interface. |
The following sections provide technical details about available prerequisite checks.
