Upgrade VMWare VSphere VCenter Server from ESXi 4.0 to ESXi 4.1

The VCenter service on my server won't stay on.
After futile efforts to resolve the issue, I decided to create a Virtual Server and install VCenter on it.
I then added the host servers but keep getting error "vCenter does not support hosts of this type (VMware ESXi 4.1.0)"
That's because the current VSphere server is 4.0 but the Hosts are already 4.1
I downloaded the upgrade file but there's no executable to run.
How do I upgrade VSphere server application?

VMware vSphere vCenter Server 4.0 is upgraded, by inserting the 4.1 media into the server, and running the setup program. It will detect the existing installation (4.0) and upgrade the database and server components.

It is true, your vCenter Server *MUST* be the same or a higher release version that the hosts it manages.

So you cannot use vCenter Server 4.0 to manage ESXi 4.1 it's not compatible.

Thanks for the quick response.

I downloaded the upgrade files but there are no executables to run. This server is on a HyperV host. I mounted the ISO but there is no autorun file to launch

Upgrading to vCenter Server 4.1
Note: You can upgrade to vCenter Server 4.1 from VirtualCenter 2.5 Update 6, vCenter Server 4.0, and vCenter Server 4.1 for any Updates. Before beginning the upgrade:

    Confirm that your database is supported with vCenter Server 4.1
    Back up your supported database, SSL certificates, and vCenter Server configuration.

To upgrade to vCenter Server 4.1:

    Download the VMware vCenter Server 4.1 and modules media from the vSphere Download Center.
    Extract the ZIP file onto the vCenter server or burn the ISO to a CD/DVD-ROM.
    Launch the Autorun within the vCenter Server media and choose to install vCenter Server.

    The installer informs you that there is an earlier version of vCenter Server on the computer and that it will be upgraded.

    Continue through the wizard to upgrade vCenter Server.
    Reboot your vCenter Server.

I saw that link but there's no "Autorun" file in any of the upgrade ZIP or ISO file

Can you upload a screenshot of what you have, there should be folders and files, and a setup program, and the Autorun!

Those files are incorrect, those files are to updated ESXi 4.0 to ESX 4.1.

You need vCenter Server 4.1.

Make sure you check the ISO downloaded, the MD5SUM signatures is correct.

there's an application here in my EE Article, and shows you how to do this, mount the ISO, run the Setup, and just click Next, and follow the wizard.

Part 4: HOW TO: Upload an ISO CD-ROM/DVD-ROM image to a VMware datastore for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client, and checking its MD5 checksum signature is correct.
