Fail to install window services,

Question

I have written a window service testaaa.exe (from template). when running installutil.exe testaaa.exe, i get the below output and there is no service added in the server explorer. /*###########################################*/ Running a transacted installation. Beginning the Install phase of the installation. See the contents of the log file for the c:\temp\service\testaaa\bin\debug\testa aa.exe assembly's progress. The file is located at c:\temp\service\testaaa\bin\debug\testaaa.InstallLog. Installing assembly 'c:\temp\service\testaaa\bin\debug\testaaa.exe'.
