Server Requirements for 9.5.1

Question

I am currently running 2003 x64 sp2 on my main and hotstandby NPM servers.  My current version of NPM is 9.1.  I want to upgrade, but I noticed that the requirements for 9.5.1 state this:

Windows 2003 Server (32-bit or 64-bit, with IIS  running in 32-bit mode) R2
IIS must be installed.

I do not have R2. Will this upgrade still work?

Thanks.

R2 is not required, or implied required to be supported. I'm running 9.5.1 on straight Windows Server 2003 (Not R2) with no issues.
