Win 7 RTM X64 - Net 3.5 SP1 fails

Question

I've had some weird issues with Visual Studio 2008 - Got a tips from another forum to check the health of my .NET install. So I downloaded Aarons .NET Verifier tool. Net 2(sp2) and .Net 3 verifies: OK, but 3.5 SP1 fails.

I removed 3.5 sp1 via "turn on/off windows features". Reboot - "turn on" - and it started installing, hung about 98% done(I left it going over the night). Reboot - Net verify still fails on 3.5 sp1

So what to do? I can't install any "other" 3.5sp1 package?

Please advice!

TIA!

Regards,

  Lars Siden

Answer 1

Hi Lars

Can you see the option "Microsoft .NET Framework 3.5.1" in "Turn Windows features on or off" under control panel?

The .NET Framework 2.0 SP2, 3.0 SP2 and 3.5 SP1 are all installed as OS components on Windows 7, we cannot uninstall them from Win7 but to disable them.

As for verify tool, please use the one that with Win7 support: http://blogs.msdn.com/astebner/archive/2009/07/27/9850215.aspx

Thanks!

Hello,

I have used the windows feature to turn 3.5.1 on and off to "re-install" it with win 7. If I check both non-http-activation and http-activation under 3.5.1 the installer never finish(may be related to some IIS 7 setting?)

I'll test the new win 7 verify tool.

I have now tried the new verification util(it was the one I already got).

I found the "error log file"

So why don't I have NPWPF.dll?

Cheers, Lazze

Answer 4

I sort of solved it. I copied

 C:\Windows\Microsoft.NET\Framework\v3.5\Windows Presentation Foundation

From my Win 2008 x64 dev server to my Win 7 x64 installation. Now the verify util says "OK"

Maybe this has some other ill effects?

Cheers, Lazze

Answer 5

Hi Lazze

As .NET Framework 3.5 SP1 is a Windows Component of Win7, in case of any problem of .NET Framework installation, you may need to repair the Win7 to fix it (use the cmd prompt: sfc /scannow )
Here is an article for details of how to fix .NET 2.0/3.0 in Vista, the steps can still be applied to .NET 3.5.1 in Win7: http://blogs.msdn.com/astebner/archive/2007/03/26/how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx .

If you have any specific problem, please feel free to let me know.

Thanks.
