I am running Windows Server 2008 R2 Standard edition at the moment I have IIS 6 installed.

I need to update IIS to version 7.5.

Using Server Management under Roles, I can see Web Server IIS Installed. Using Web Platform Installer I can see only IIS 7.5 Express.


How can I upgrade to IIS 7.5? (normal version - not Express) Could you please provide some instructions?

IIS on Windows is version-locked. This means that 1 version of IIS ships with a specific version of Windows and that's it. If you want to change IIS, you need to change your version of Windows.

This matrix might help

IIS 5   -   Windows 2000 Server
IIS 6   -   Windows Server 2003
IIS 7   -   Windows Server 2008
IIS 7.5 -   Windows Server 2008 R2
IIS 8   -   Windows Server 2012

Generally speaking IIS Express isn't installed on a server, because there's no need. If you're working with an existing Windows 2008 R2 server that has the IIS (Web Server) role installed, you're working with IIS 7.5


There is no IIS6 on Windows Server 2008R2, and it is not possible to install it there. So you already have IIS 7.5.

IIS 7.5 express is an application, not a service, it does not show up in Server Management, both Express and the full version can be installed at the same time. There is usually no reason to install Express on a server. It's used to development on workstations.
