[JIRA] Commented: (SSPCPP-499) Fresh Installation on Windows XP fails after service daemon fails to start

Scott Cantor commented on SSPCPP-499:
-------------------------------------

IIS doesn't need the notification for the installer to work as long as it reboots before use. If the problem is that it needs to check for a pending restart and block installation, that's doable I would think. I don't know what else we could do, and I'm not really inclined to spend much time on XP. I'd sooner just drop support for it officially.

>             Project: Shibboleth SP - C++
>          Issue Type: Bug
>          Components: Installation / Packaging
>    Affects Versions: 2.5.0
>         Environment: Windows XP Pro SP3 (Czech), IIS5

> Symptoms:
> After "Starting services" the installer rolls everything back with general error message "...Setup Wizard ended prematurely because of an error. Your system has not been modified." In system log there is error id 7009 (Timeout for shibboleth 2 Daemon) repeated 7 times.
> Problem:
> The problem is caused by 2 circumstances:
> 1. The installation relies on starting the service daemon (shibd.exe) during installation to succesfully finish installation.
> 2. The installer updates the %PATH% during installation, but it can't immediately update it's instances in all running processes. The updated dll path (%PATH%), which shibd.exe needs to start is reliably updated only after reboot OR slightly less reliably when the installation completes and the installer sends WM_SETTINGCHANGE message. This message however is not sent if restart of the system is pending. See:
> http://msdn.microsoft.com/en-us/library/windows/desktop/aa372883(v=vs.85).aspx
> I have observed this only on Win XP.
> Workaround:
> Add the shibboleth library path (typically C:\ProgramFiles\Shibboleth\SP\lib) to system %PATH% manually and reboot before starting the installation.
