Is it possible to install .Net 4.5.2 on a clean Windows 7 without any service packs installed?

I am asking since the release notes for 4.0 state

- Windows 7
- Windows 7 SP1

while the 4.5.2 only state

- Windows 7 SP1

However, the accompanying text on the download page says

The Microsoft .NET Framework 4.5.2 is a highly compatible, in-place update to the Microsoft .NET Framework 4, Microsoft .NET Framework 4.5 and Microsoft .NET Framework 4.5.1.

So, what is the case now? Is it highly compatible and can be installed on Windows 7 (no sp), or can it only be installed on Win7 SP1?

  • Technically speaking, it should work. But may I ask why you have this question? Are you not going to install SP1? – LPChip Jul 24 '14 at 10:29
  • I have to create an installer for an application that requires .Net 4. I thought it might make sense to bundle the latest web installer for ease of use, but some people might install the app on non-SP1 windows and I don't want to force a dependency on SP1. – Wilbert Jul 24 '14 at 10:33

    The simple answer. Don't provide support to Windows 7 RTM. The requirements are pretty clear – Ramhound Jul 24 '14 at 10:37
  • But then the people running Win 7 without SP1 might not give us money. – Wilbert Jul 24 '14 at 10:43

    I guess some people here are missing the point: There is no such thing as “we don’t support it” with enterprise software development. You think you can drop support for Windows XP or Office 2000? Wrong. You can’t. Big companies are nigh immovable behemoths. Even a single patch could take months of testing. – Daniel B Jul 24 '14 at 12:06

Right now I was able to install .Net 4.5.2 on Virtual Machine with clean Windows 7 x64 (no SP1) via web installer.
