Dot Net Framework question

[Starrx05]

If I have ver 1.1 on which I think it came w/ Office XP, when I put on 2.0, should I remove it or I can have multiple versions on my laptop? A new app I'm installing need ver 2.0 I read somewhere that apps requires the dot net framework will need to have exact version of it. It takes up space so I want to remove the old one if that doesn't affect any apps that are using it.

2.0 is backwards compatible with most applications but not all, you can and should install it side by side. 1.1 applications will use the 2.0 framework if it can, and fall back to the 1.1 framework if there are breaking changes.

There is a lot of confusion over this. You need all the versions of the framework installed side by side, preferrably having installed service packs for one version before installing the next, if you want everything to work correctly. I recently did an install of 3.0 on a clean system, and it installed and patched 1.1 and 2.0 as well.

Bingo 🙂 They are expected to be installed side by side, unlike things such as DirectX where each new version replaces the old...

Thanks everyone. I remember reading Microsoft saying you can have multiple versions of this together, not like the service pack which you only need the latest and it will cover everything. I have WinDVD on Win XP Media center and it uses .NET 1.1 An app I'm installing needs 2.0 so that's why I was asking. So installing 3.0 will also put 1.1 & 2 on and all the patchs? Interesting.....
