Activating Windows features (IIS) from InstallScript Project

[alejandrogarino]

Hello,

I'm working on an InstallScript project and I need to set as prerequisite that the user must have the IIS installed and activated.
Is there a way to achive this from inside the project?
Otherwise, which would be the correct way to do this?

Thanks in advance.

Alejandro

Alejandro,

With InstallScript, you could try something like this:

    OBJECT  objIISRoot;
    ...

    // Check for IIS 
    try
        set objIISRoot = CoGetObject("IIS://Localhost/W3svc", "");
        if IsObject( objIISRoot ) then
            //IIS is installed; might want to check version number
        else
            //error: Couldn't verify IIS (couldn't get root virtual directory)"
        endif;
    catch
    	//error: Unable to verify the existence of IIS on this system.
    endcatch;

To verify that the IIS Admin and W3SVC services are not disabled, check these registry keys. A "Start" value of 0x00000004 means the service's startup type is Disabled. You can test the value by just comparing it to "4".

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\IISAdmin
[Start]

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W3SVC
[Start]

Thank you ch_eng for the answer!

Where should I put this code? I mean, in which event would it be the best place to make this validation?
On the other hand, is there a way to install or activate IIS by code in case he doesn't have it?

Thanks!

Alejandro,

I would recommend checking for this near the beginning of:

function OnFirstUIBefore()

Sorry, I do not know how to install or activate IIS if it is missing.

what version of IIS are you using? Or rather, what server? For IIS 6 (Windows Svr 03) you can use

Sysocmgr.exe /i:[WindowsFolder]inf\sysoc.inf /u:[SUPPORTDIR]\IISAnswer.txt

I haven't yet looked into the IIS 7/Svr08 method, but whoever gets to it first should update this post. I think Svr08 comes with the IIS role already enabled, but it's been a while since I last set a Svr08 machine up, that I don't remember.

Oh, as for detection, look in

HKLM\System\CurrentControlSet\Services\W3Svc\Parameters
Name: MajorVersion

if you find a 6, then IIS 6 is already set up.
