I received Microsoft .NetFramework 1.1 Service Pack 1 as an automatic update. Whenever I try to install it, it keeps telling me "The update could not be installed". The icon in the taskbar keeps reappearing. Wolfgang Harles
Sometimes updates won't install because of problems with the version you already have installed. The simplest approach is probably to use Add/Remove Programs to uninstall .Net 1.1 and reinstall it from a fresh download.
However, version 1.1 came out in 2003 and is out of date. It would be better to install .Net version 3, which includes new technologies shipped with Windows Vista. If you go to Windows Update (windowsupdate.microsoft.com) and click Custom, this will check your PC and it should appear as a recommended update.
There is a minor update for .Net 3 (see KB932471), which you can ignore, but version 3.5 is now being beta-tested.
