I understand, but I cannot uninstall the 2.2 using the add remove program.

Sorry about the 2.2 put it down to old age,

it should have read 2.0.

On trying to repair or uninstall in the add remove program, I get the following message.

HEADER.

An error occured during setup.

Patch package could not be opened. Verify that the package exists and that you can access it, or contact the vendor that this is a valid Windows patch package.

Have removed the 1.1 and the hotfix.

Thanks

x86 is for 32bit operating system

x64 is for the 64bit operating system

I'm guessing  you got a 32bit ;)  

Thanks for all the help. I have tried the 3 first items on the  article 908077 with no joy, I am about to try 'Run the .NET.Framework 2 Redistributable package at a command prompt' just to be sure, there are two packages,

1.(x86), 2.(1A64), which one should I use.

Thanks a lot.

I have down loaded the dotnetfx file to the desktop, but on pasting the command at the command prompt I get the following message, 'the system cannot find the path specified'what am I doing wrong?

%InstallationPath%\dotnetfx.exe /t:%temp% /c:"msiexec.exe /fvecms %temp%\netfx.msi"

Thanks for your patience.

If I have to manually remove the 2.0 as the instructions on the same article, to what extent would you think the security risks to be, the paper suggests one should evaluate them fully.
