  • @SergeyBerezovskiy but xp doesn't support .Net4.5. So answer is **no** you can't. Even if you manage to do there is no guarantee that it will work properly – Sriram Sakthivel Mar 07 '14 at 07:58

    You must install .net 4.5. Here is post on if and how to do it '[Is it possible to run a .net 4.5 app on XP?](http://stackoverflow.com/questions/17499351/is-it-possible-to-run-a-net-4-5-app-on-xp)' – pen2 Mar 07 '14 at 08:01

    I think it is a valid question as it refers to which SP to use – Rami Mar 07 '14 at 08:04
  • @RamiHelmy I think suggested duplicate is also valid since whichever SP you use doesn't matter when msft don't support it officially – Sriram Sakthivel Mar 07 '14 at 08:06
  • @SriramSakthivel, no objection. let's wait for the votes. – Rami Mar 07 '14 at 08:15
  • Yes, it is possible you need to install one core api: https://github.com/Skulltrail192/One-Core-API-Binaries the you can install .NET up to 4.8 – Stefano Balzarotti Aug 04 '23 at 06:44

It is not possible. You need to install .Net 4.5, but this is not supported for XP.

Bottom line; It is possible to install and run .NET 4.5 on Windows XP (Service Pack 3) but it is not officially supported and your app will probably experience some problems.

The system requirements for installing .NET Framework 4.5 is listed here:

http://www.microsoft.com/en-au/download/details.aspx?id=30653

As you can see Windows XP is not listed as a compatible OS

Check that support ticket too.

and the answer to that question too:

Is it possible to run a .NET 4.5 app on XP?

  • Windows 7 SP1 (x86 and x64) Windows Server 2008 R2 SP1 (x64)
  • Windows Server 2008 SP2 (x86 and x64)

Hardware Requirements:

  • 1 GHz or faster processor
  • 512 MB of RAM
  • 850 MB of available hard disk space (x86)
  • 2 GB hard drive (x64)

XP is not listed.
