Thanks Drew it worked for me in VISTA SP2 after I've got various errors and after trying ALL EXISTING SOLUTIONS found on the WEB ( except reformat ).

I even delete "accidentally" NETFramework folder from windows in a stupid ultimate attempt... to make a clean install

Any update to 3.5 or 3.5 SP1 was rejected at last at 99% with missing optional 3.0 components etc...

I lost the even viewer console than etc ...

Since it was impossible to recover the native Netframework V3.0 I tested your solution.

Merging HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework from a similar vista sp2 computer but also copying from thumb drive the whole C:\WINDOWS\Microsoft.NET folder and subfolders was fine and I was finally able to install/update the evil .Net

1) clear all versions

2) Delete %TEMP% folder content

3) Reboot

4) Copy all mscor*.dll from SYSTEM32 from a similar computer with uptodate Vista SP2 ( if dll are different and If the system don't let you do that just boot from an alternate sytem like a CD or Ubuntu and forcefully replace them )

5) Merge HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework from another SP2 Vista computer

6) Merge C:\WINDOWS\Microsoft.NET from same computer

7) REBOOT

7) Apply standalone .NET updates 3.5

8) Reboot

9) Same with 3.5 SP1 and KB fixes

10) Reboot ;-)

THANKS ALL for the tools and the tips !

I've had success with the following method:

- Use the .NET Removal tool found on Google and remove all versions then reboot.

- Next find a computer with the same OS and Service Pack, in my situation XP SP3. Copy C:\WINDOWS\System32\mscoree.dll from that computer to a thumb drive.

- On that same computer open REGEDIT and go to HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework and Export that onto the thumbdrive with any filename.

- Right click the .REG file on your computer and select merge. Also copy that mscoree.dll from your USB to your C:\Windows\System32 folder.

if you have corrupt files, personally I would re-load the OS. Do you know how you got corrupt files? If not, then there is a risk it will happen again. Try the MS security scanner and see if some nasty is on the system.

Thanks

Thank you for suggesting the three step directions to resolve the Microsoft.Net framework issue. But it did not resolve my problem as the first step I did via sfc/scannow showed that my computer has corrupted files. So please advise what I need to do before I could go on with the step #2?

I had a website that would crash with a .NET (2.0) error, and no amount of fixing I did repaired the problem - these instructions worked like a charm! THANK YOU!

I had a corrupt System.Web.Dll (zero size) in the 2.0 framework folders on my Windows 7 machine that was causing all my issues (mainly with VS2010). Tried everything here to repair it but no luck. Ended up taking ownership and replacing the corrupt file with a copy from another machine.

Also tried all sorts of repair/reinstalls of the 2.0 framework but absolutely nothing worked. What a nightmare.

All good now though, AFAIK.

Brad,

I found the commands worked just fine on my system replacing Framework with Framework64.

Thanks

Is there a comparable repair command for the x64 framework folder?

%windir%\Microsoft.NET\Framework\v2.0.50727\ngen.exe update

part of your solution

Thanks

Vista has .Net framework V2 built in, so there is no download needed.

Thanks

ER.... vista 7 beta failure: After I tried to install the 2.0 sdk and fiddled around with starting a few (of the nearly 1,000) services.

to wit:

All compilation targets are up to date.

From ngen.exe update (as you directed, kind sir). I'm wondering if it can really not find it or if it's a victim of your Novell-on-Acid rights inheritance schema. Ah, oh... did the sfc as well. Does it just look at files or also the securities on them?

I'd kind of like to fix this because (kudos to MS and in a big way) this beta is more stable than the v6 I have on my other drives. Not too crazy about a few features and it sticks once in a while but guess what, no bsods. Now that's a major upgrade! (no sarcasm implied -- I am impressed so far).

By the way, your level 2 and 3 tech support is superb. Had to bring in a 3 for a 07 bsod with a gigabyte motherboard (they denied everything and hinted it was NVIDIA's fault- which is probably true).
