Command Line Operation of the Prerequisite Checker
You can run the prerequisite check silently by executing
runprereqchecks.exe /s from the \windows\PreReqChecker directory. After running the prerequisite check, an HTML file will be created in the %Temp% directory. The file is named omprereq.htm, and it contains the results of the prerequisite check. The Temp directory is not usually X:\Temp, but X:\Documents and Settings\username\Local Settings\Temp. To find %TEMP%, go to a command line prompt and type echo %TEMP%.
The results of the Prerequisite Checker are written to the registry for the Management Station under the registry key:
When running the Prerequisite Check silently, the return code from runprereqchecks.exe will be the number associated with the highest severity condition for all of the software products. The return code numbers are the same as those used in the registry. Table 10-1 details the codes that are returned.
