NET Framework was unable to update from Windows Update. Looked for an answer and tried several solutions, none of which worked. First I tried uninstalling all of NET F with dotnetfx_cleanup_tool. Then I tried to get NET F back from Windows Update but the installation would never complete although it seemed like it was installing. Then downloaded dotnetfx.exe and same thing. It started to install but wouldn't complete. Can't get updated NET Framework back. Any suggestions??

Thanks,

Need more infos from you before help can occur.

1. Service Pack?

2. Architecture?

3. Admin rights?

4. Also check event viewer for errors.

1. SP3

2. What do yo mean by "architecture"?

3. Yes, using administrator account

4. Error was 0x66A before uninstalling, and 0x641 after trying to reinstall.

The installer leaves a log file behind (in %temp%, called dd_dotnetfx*.txt IIRC). I'd have a look at that instead (open with notepad, ctrl-F, search for "error" or such -- you should find something quickly)

Looked in dotnetfx folder. There was no log file there. Did a search for it and nothing came up.

browse the GUIDs in

HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall

should be able to get the msiexec /x{guid} string for any left over pieces. We had a video driver that dropped a version of netframework2.0 I had to uninstall via this method.

Looked in dotnetfx folder.

I said in %temp%. If you go there, you will find a log file.

Is this it Coffeefiend? This is the "dd_dotnetfx35error.txt file.

There are also a log file and a depcheck file it they would help.

I concur with iamtheky.

Sorry but I have no idea what to do with Iamtheky's response.

go to START-->Run

type regedit

browse to

HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall

you will see a bunch of folders underneath generally titled with the GUID of the product installed

when you highlight one of the folders the contents will display in the right hand pane

start scrolling through them looking for a displayname that is = to some .net action

then copy that uninstall string and paste it into a cmd window

*again, if its a /i that will usually be the repair/remove dialog, use /x for the straight uninstall dialog

I found 3 seperate folders with "display names" that refer to NET Framework 3.5 with uninstall strings. Should I put the uninstall string for each one into a cmd window? There is also a folder that refers to an icon for NET Framework. Do I need to be concerned with that or leave it alone?

yeah I would certainly run them all.

I did not clean (nor even look for that matter) for orphaned pieces. Once I had uninstalled the existing pieces via this method, the .net installations resumed normal behavior.

To Iamtheky,

I am unable to copy and paste the actual string. When I click on it, it won't highlight. The Edit menu only lets me copy the "key name". When I copy and paste that, all it does is paste the location with the KB# but not the actual uninstall string.

Also, the last instruction from your previous reply which was, "*again, if its a /i that will usually be the repair/remove dialog, use /x for the straight uninstall dialog", I don't entirely understand. I didn't see /i or /x in the string itself, the part the wouldn't allow me to copy and paste.

Thanks for the help

I apologize, some of those entries are a bit incomplete.

Go ahead and type the following into a cmd prompt

msiexec /x{that-key-name}

it should work for most as the folder is generally named the same as the GUID.
