Вот исправленная версия сценария установки, который я написал. Должен продемонстрировать все, что вам нужно сделать:
## delete existing service
# have to use WMI for much of this, native cmdlets are incomplete
$service = Get-WmiObject -Class Win32_Service -Filter "Name = 'My Service'"
if ($service -ne $null)
{
$service | stop-service
$service.Delete() | out-null
}
## run installutil
# 'frameworkdir' env var apparently isn't present on Win2003...
$installUtil = join-path $env:SystemRoot Microsoft.NET\Framework\v2.0.50727\installutil.exe
$serviceExe = join-path $messageServerPath MyService.exe
$installUtilLog = join-path $messageServerPath InstallUtil.log
& $installUtil $serviceExe /logfile="$installUtilLog" | write-verbose
$service = Get-WmiObject -Class Win32_Service -Filter "Name = 'My Service'"
# change credentials if necessary
if ($user -ne "" -and $password -ne "")
{ $service.change($null, $null, $null, $null, $null, $null, $user, $password, $null, $null, $null) | out-null }
# activate
$service | set-service -startuptype Automatic -passthru | start-service
write-verbose "Successfully started service $($service.name)"
