Install dotnet 1.1 over 4

Does installing Dotnet 1.1 after 4.0 give any head a开发者_Go百科ches?

I have a machine with Dotnet 2, 3.5 and 4.0. Now there is a need to install Dotnet 1.1 too.

Are there any steps I should do before? Will the installation hate and haunt me? Will all run smoothly?

.NET 1.1, .NET 2.0 and .NET 4.0 can all be installed side-by-side.

You might run into oddness in the following areas:

1. The 1.1 installer might be broken and fail to allow this.
2. It might break (e.g.) your ASP.NET installation.
3. Up to this point, installed applications targeted against .NET 1.1 will have been using .NET 2.0 or .NET 4.0. Once you install 1.1, they might start using the correct (old) version. It might be subtly different from the newer versions.

I have tried installing 1.0 and 1.1 after 2/3.5/4 now. And everything seems to work normally.

Update: 1.0 and 1.1 where not installed even though c:\windows... had the frameworks in it. I tried to run a 1.1 application and it complained. I installed 1.1 and the application worked. (so I "know" it wasn't installed beforehand)
Now I will run for a while before I can say that installing 1.1 after 2/3.5/4 will work.
